OSCommerce Shipping Zone Fix & SSL Setup

Hi, I'm looking for a freelancer to do immediate, and then ongoing, work for me. My immediate need is to fix the OSC shipping module ([login to view URL] file) to allow for multiple-zone shipping rates, and to install an SSL certificate (I have the code). I don't think this will be more than a couple hours of work. The modifications will have to be applied to 2 websites. I'm thinking $20 to $30 for this project, as I doubt it is longer than 2 hours work. With that in mind, I need to have an OSC expert "at hand" that I can send business to each week... so please let me know what your hourly rate is for making modifications etc. I have multiple sites, and will pay you thru GAF each time I need your services. If you are a designer, even better. So bid on this small project, and show me your speed and skills. If you're good, this will be the beginning of consistent work forward. Thanks!
