Congrats! Getting there is no easy task.
What to do next, I have no idea, I'd certainly consider doing the obvious and posting the first 5 or 10 pages in Screenwriting SYW, and consider doing the same on
DoneDealPro. Feedback on the first pages can often be applied throughout the screenplay!
If you haven't already, consider signing up to the
InkTip weekly newsletter. If you want to look at the free version first to get a feel for the kind of tips they offer, the link's at the bottom of the Preferred Newsletter page. Look at their other products, too. Their success rate re putting screenwriters in contact with prodcos seeking scripts keeps rising.
Post #3 in the screenwriting tips thread makes a poor attempt to list sites and services where you can find more info on prodcos willing to receive queries (in logline form, usually) and contests open to submissions. The latter cost money, by and large.
Talking of loglines, have your elevator pitch ready in case someone asks. You never know who you might trip over on your quest.
