about getting an agent. i always give the same advice whether it works for you or not i don't know but...
an agent is not looking for a "one hit wonder". you'll need a few more marketable scripts under your belt to attract a good agent b/c they only make money from the sale of your scripts (or writing assignments which is a different matter).
if you have only one script which is market-ready* then you could possibly get lucky with finding an agent who knows a producer who is looking for exactly what you have to offer. but, it is probably better for you to submit to producers who are looking for that perfect script that you have.**
the catch-22 is that many producers (but not all) will only take submissions from agents (not writers and esp not newbies). therefore, you will most likely need to get an agent first. however, if you find a producer who does want your script then it will make it so much easier to find an agent because you have already done the leg work for them (finding a buyer) and they will get paid to do nothing but a little paperwork
*knowing whether your script is market-ready is an entirely different problem that you MUST deal with first.
**finding out what producers are looking for is another process of marketing that is easier than finding an agent. you just have to know where to look.
now... go write another script because your first one is crap!
