PHP & MySql Services

I have a website and I want to put some badges and quests to give more dynamism. I do not need webdesign, only the codes in PHP and MySQL I made a PDF explaining the tables and the pages I need. Sorry if you find any technical error, I only created this document to facilitate understanding for the freelancer. The pages and webservices are very similar. All Pages need a webservice that return a json to work on the html. For example, the “[login to view URL]” on the directory “webservices” return a json. On the directory “site” the “[login to view URL]” show the basic html created with the json. Webservices, only need to return “1” or “0;message” Admin pages have to list the tables itens and allow to add, edit and delete (using ajax or another technology to not refresh the page when i do a update). I'm not hurry to develop. Please contact if you have any doubt.
