My company has developed a online script which shows students step by step how to solve math problems. The issue is we want to keep it free to the public but funding it is the problem.

At the moment, the only way we have come up with is companies paying for sponsorships.

So any other thoughts on how my company could fund it; that would be great. Also, if your company is interested in sponsoring; let me know.

The site is:
TeachExplain.com - A calculator which shows step by step how to solve math problems.

I hope in the future to add algebra, trig, calculus, and any other math subjects which could help students.

Last, any thoughts on the script itself or design are more than welcome.
