The problem with approaching publishers about offering games at discount prices is that you need to be able to guarantee enough traffic to make it worth it to them, because if they don't get a high amount of traffic then they are losing money.
It's of course your choice, but I would advise waiting to approach game developers until after your community has been up and running for at least a year, and has a large active userbase. That way you don't risk driving them away in the future.
((As for design1online she is already going to be offering her framework at a very low, very reasonable price and asking her if she'd be willing to offer a discount could potentially be insulting to her, as the work she is doing is already worth far more than $300)).
Not trying to discourage, just advising to help
