Need a Coder for $20 for 2 simple Tasks

Hello i will be paying someone $20 to put my WHMCS System in the design of www.powerbx.com and use Iframe/ajax to make it when they click on the button at the button so the page wont reload..

I don't get what you're asking for about the Iframe/AJAX...

he means so that section alone will just update instead of reloading the page.
First thing for $20 you won't get any AJAX done imo. You can put it in a frame to stop the rest of the area updating and just leave the WHMCS System to update.
