Debug PHP Script on BTC exchanger - open to bidding

I need to debug and add new functionality on a BTC PHP script on bootstrap that is already installed and working. Below are the defects I noticed on the script: 1. Currency converter uses Google url api ( [login to view URL]) is not working though it display and updates current price. 2. Two buttons that suppose to perform specific function (release btc and send btc) are not working. They are clickable, but do not perform requested call. Then, these buttons should flow through two factor authentication path before delivering the purpose of call (clicking). Two factor authentication script already present. 3. Embedded two-factor authentication needs additional tables on database to function properly. 4. Notification of trade and payment via mobile phone text message and mobile phone verification not working. 5. Embedded security flow on some buttons is not working (Like report trade and payment buttons). These are the things I want done on the script. Like I said, the script is working, but these features are not working king on it. NB: I attached screenshots of the site where currency converters to other currency is working and my script where it is not working. Just to have an idea of what the site looks like.
