Project for Facebook Experts

Hey, This is the project for Facebook + PHP experts only. This is related to Retargeting, if you don't understand it,please have a look: >> [login to view URL] There are 2 options i need: 1) Front end: This should be a PHP script, where member can login. and create campaigns. Fields like Campaign name, ID, etc should be used. and then with every campaign, there need to be GET ID button, i'l explain the get ID purpose. 2) Admin end: Here only admin can login, check member's, delete/ban/email current members. CORE System: On creating a 'campaign', user should get 2 set of codes: 1) CODE 1: This user need to paste in his sales page/front end of his website 2) Code 2: This code user have to paste on his 'end' pages like 'Thank you page', download page etc Process: Process is, using CODE 1, the script need to get the ID of the facebook user (that could be done through the browser's cookies or probably this:>> [login to view URL] ) now, script should save the 'name' and 'ID' of user as .TXT, which is downloadable through GET ID button, in every campaign. HOWEVER if the user visites the 'thank you' page of website (means the page which have Code 2), then ID and username should be saves under another button called 'Buyers' In nutshell, i need a system through which we can save facebook user's ID and Name, who visit my website, in the MySQL database. Per my knowledge,it could be done either by checking the 'browser's cookie, or using this facebook tool: >> [login to view URL] Let me know if you have any question. My Budget is: $500 MAX
