Implement Linkpoint Payment System

Hi everyone, I have a custom PHP site that is now fully developed, but I have two items to resolve before I can launch it: 1. Troubleshoot search feature -- was working fine just a couple of days ago, so it's probably something simple. 2. The site is already configured to capture the user's personal data, credit card data, and charge amount -- now I just need to get the transaction sent into the Linkpoint system and process a response back. I have the full info from Linkpoint including sample code, I'm just not sure which code I need. Need this work done asap, the sooner the better! Please be priced affordably! Thanks, Terrence
