Thanks for all the feedback. After I posted this I found the comic
Ratfist by the creator of Earthworm Jim. He has the first 51 pages of the 176 page graphic novel on his site to read. Not a bad way to go.
Was looking at Image's digital method. Would be the ideal company to go through but I don't care for how they handle the digital side. $3-4 (same overpriced price as a physical copy) and then down to $2 after the issue has been out for a while. I wouldn't want to charge more than a buck an issue. Dunno if there's a way around that with them.
Maybe release the first two or three issues or so online for free, have the first six collected to sell as a trade and then go monthly from there. Still...pretty expensive if go through Image (but I would have to pay a colorist and letterer as well so needs to be fair to them). Shall see.
