I need an AJAX wizard. Please read carefully before responding

I just need one quick function, it may lead to other work but for now I need someone to answer quick and be able to have this working withing the hour. The Setup: Wordpress Contact Forms 7 w/ Dynamic Inputs The Problem: I need to click a button or link generated by php with a php variable There are some popup steps in between Then contact form 7 loads it's form I need to use a PHP variable as value of the CF7 form and I believe this needs to be done by AJAX, and I have no idea how but need it working today I have already setup the form to read HTTP GET variables and it works via that method, or it can already read a shortcode as the variable, but I cannot pass the variable without using a cookie and do not want to use a cookie. If you know what I am talking about and are familiar with Contact Forms 7 and AJAX, and can start right away, please message me and we can chat and get started. Thank you, Freelancers
