I do have some actors who are interested in it, friends mostly. Right now I just need somebody to produce, who will take what I have to offer with a screenplay? The concept is good, people seem to like it, but I need to find a producer because they are easier to pitch to, agents sometimes, but most of the time they don't trust in untried writers, that is not part of their job, their job is to work with people who will earn them money, and right now that is unsure at best. I can appreciate what Kullervo is saying, but I'm am not in the least bit ready to give up on this, I shouldn't have to. I want to fight for it until there is absolutely no option left to me and it's best to let it die. But not now. I'm gonna keep trying.
Okay, first you need to understand some professional terms, because the word "produce" can have different meanings depending upon where you are in the process.
If you already have the financing in place and you're looking for someone to "produce" your movie, you're looking for someone to "line produce" -- that is, to do the nuts & bolts job of actually putting together the thousand and one pieces of the puzzle that make a movie happen.
On the other hand, if you've just written a script and you haven't sold it yet, you're not so much looking for someone to "produce" it, per se - as looking for someone to "buy" it. Ultimately, of course, the goal is to have it produced, and if you're script is better and more commercial than around 50,000 other specs written by other unproduced writers and better than several thousand produced and sold writers, that may possibly happen -- but it's not generally phrased in that way -- that you're "looking for a producer."
Basically, the goal of a "screenwriter" is to make a sale -- to either have a script optioned, or sold outright. Almost always, you would sell your work to a development company. If you're lucky, to a company that already has some source of financing in place -- but most don't.
That is, they have enough money to pay their staff and to option material (pay a fraction of the purchase price to hold onto it for a certain length of time) -- which they, in turn will go out and try to package (that is, attach a director or a star to) and go out and sell to somebody who actually has the money to make a movie.
And rest assured, no one that you will be selling your script to (presuming that you can find someone willing to do it) will be interested in casting your friends, unless you happen to be friends with Bruce Willis or Anne Hathaway.
You'll be lucky if they're even interested in having you remain attached to the project to do the rewrites which they will inevitably be asking for.
The only real alternative to the above is for *you* to take on the role of producer, which means that you have to actually raise the money to make the movie yourself. How? Beats me. I've never done it, but people do.
And the overwhelming majority of those people, who raise money and use it to make their own movies, lose that money, because the movies that they make, for the most part, prove to be unreleaseable.
That's not terribly surprising. When you consider that they're generally based on screenplays that the writers in question couldn't sell, no one should really be shocked that when those same writers raise the money, make those screenplays into movies, and go back in the hopes of getting a distributor that they can't find one -- since they're basically going back to the same people who weren't interested in their scripts.
The same reason that those people had for saying no to the screenplay will generally apply to any movie made from those screenplays. Only now, instead of having a screenplay rejected, for which the writer has only lost the time and effort of writing a screenplay, now he's lost all of the time, effort and *other people's money* -- and often his own, that he's invested in making a movie that will never be released or show any profit.
And given the proliferation of low-budget cameras and digital editing, there are now literally thousands of such unreleased and unreleasable movies produced ever year -- movies that will never be seen outside of youtube and never make anybody a dime.
So both routes pose major challenges. Personally, if you can't get someone interested in buying your script, I think that it makes very little sense to attempt to produce it on your own.
If you're going to attempt to sell it, there are various ways to go about doing it, and a search of prior posts asking that very question on this board will probably give you a sense of how to go about it.
But you should understand that, at best, it is a highly competitive market, and a very steep climb for anybody to get a project sold and produced.
