I am trying to be nice when I say this but:
Being a partner takes time and work, your going to have to fix a lot, I mean a lot of bugs players find, add new mods, do updates, keep the game fresh, fix layout issues, make sure mods are working properly, ect.
Its nice that you are willing to help, but your going to need to know a lot more, and its also impossible to be available 24/7 so do not put that in, also you might not get any people interested because you tried selling a game for $10 which does not sound good.
Look into learning php for half the year or something try out mods, study the mods, fix errors when you find them, and you should be getting better at it as you go.
