Hi! I would like to develop a website like Yelp or a Citation Site.
I have these companies in mind that offers pre-made code that works like Yelp:
  1. NCrypted Technologies Private Limited
  2. Crowdvox
  3. Flippy Scripts
  4. Coderobotics Infotech Pvt. Ltd.

I have some questions:
  1. Which company is the most reliable?
  2. If you have any experience working with those companies, how was the customer support?
  3. Do you have other companies want to recommend to me that is more reliable and customer friendly?
