Php Auditor Needed

Hello, We need someone to review the Php code on our entire website located at www.myhostingdeals.com. We have a very good reason to belive that there are hidden malicious scripts burried in the code which are controled from another server. One example of the malicious script can be found if you click one the buy now button and are taken to the order screen. We belive that there are at least three more hidden scripts or codes hidden in the code that we have not discovered yet. Remember that it may be burried anywhere on our website, and we belive that it is being controled from a remote computer. You may have seen a post from us yesterday regarding our homepage getting 10,000 popups per second, and we discovered a malicious script in the flash header which has been corrected by an online member here. The person who put these scripts in is a member of this forum, whom we paid $800 for the website, then he created the website, and demanded another $500 to remove the malicious scripts and protections that he hid in the script. In the US that is called Black Mailing, and is Extortion, which is a felony. The person who did it is... First Name: Sajith Last Name: K G Address : Internet Sales Promotion Group 28/123, Parapilly Lane, Panampilly Nagar City: Cochin State: Kerala Nation : India Website: [login to view URL] eMail: mail@ispgnet email: ispgnet @ yahoo . com user: ispgnet ( Probably changed now ) We have no idea how to budget a small project like this so we set it to $20-$100, but can adjust the budget and conditions warrant. Remember that we already lost alot of money from this member.
