208250 Geoclassified Scripting

I am running geoclassifieds basic and i need someone who can script it as follows. 1. have multiple user groups in admin section so i can set different prices for the users in the groups. 2. have ability to set a per month membership in a user group. 3. complete seo upgrade that i have purchased, that is to complicated for me to handle. this is also got to be a quick process as the website is already active.
