I live in Mexico city, I think you product is great!
I think this product could be very a success in a market like Mexico based in facts:
1) Mexico economy is based 90% on micro and small services.
2) Now with this economic crisis, the people is trying to figure out how to intelligent spent each peso and get more with less.
3) Just to let you know, the sizes and economic capabilities of Mexico companies are really different than in USA or Canada: A medium company of day to day services (like carpenters, bakers, etc) for us is about 15-30 people with sales of about 700 K- 1000 K USD p year, so this kind of companies would love to be rated and affiliated in your service.
