Bidware 2.95 Additions

Hello I have Bidware 2.95 which is an auction program. It has most features I want already installed and running perfectly. There are a few things I need tweaked though to make it exactly as I want it. 1. I need it to only be able to have auctions published by server admins not registered users there is a sell section button I would like to remove and only made accesible through the admin control panel. 2. I need a auto feature where when auction hits 30 seconds and someone bids it automatically goes back to 30 seconds to lengthn the auction. 3. I need a section to charge for registration fees when users signup which needs to be adjustable in the control panel. There is this feature already I just need it added on too. Also it needs to automatically recharge them This is a php based auction site run on linux i need experienced individuals who have multiple refrences. Thankyou I cant wait to do buisness with you. There will be additional things needed but for now I would like these items takn care of immediatly.
