Hi George, I also have experience in the small press, having had publications/acceptances at Sliced Quarterly, Zarjaz, FutureQuake and 100% Biodegradable among others. I'd be very happy to contribute a script towards your anthology.
I think the model of Sliced Quarterly -- slicedquarterly.co.uk -- is ideal for this sort of project. It takes the web comic-y approach of digitally publishing for free, and then crowdfunding a physical book/collection. This might not be suitable if you're looking to provide payment to everybody, but it's a great way to create a platform and have work out there.
Look forward to seeing how this project develops and, hopefully, contributing something!
