Hi there, and welcome to the Construct 2 Forums! :)
Your thread sounds interesting, I may be able to help you out. First of all, do you have specific game designs in mind, or are you happy just to give a very general concept for us to flesh out?
For a background on us:
A colleague and I are currently providing proof of concepts for porting existing flash games into HTML via Construct 2 as a proposal for a prospective client. I'm fairly new to this industry, but so far I've been able to duplicate games in 2-3 days with C2 which have taken 2-3 months for flash developers to put together.
What is your website?
I also have another business associate who is originally from Argentina who is a fluent Spanish speaker who may be interested in getting involved.
In terms of cost, if I can have as much detail as possible on the project, I may be able to provide a rough quote. We can accommodate for the fact that you're non-profit with a lower than usual rate, if you can provide us with an official commendation/reference once we have done the job for you.
