Find funding for Hispanic businesses consortium marketing?
Where can I apply for $25k to build one website with 50 Hispanic businesses all located in a 8-block business corridor in norther California?
As Tim Berman suggested Accion may be a good option to get the funding you need.
You should also consider other not-for-profit lenders like Kiva.
If you are unable to get funding this way, you can try crowdfundingthe money you need to build the website. If the businesses you are making the sites for are willing to contribute this could give you a great start.
Best of luck,
