Auction script that works and integrates

I have had some work already done (using Symfony), however, the site needs some urgent repairs. I am NOT looking to overhaul the site or start again from scratch. I only need these three problems fixed: 1. The timer doesn't work. I have modelled my site around penny auctions (the only difference is that, in regular auctions, the price is fixed --- doesn't go up or down as bidders bid) and I need the timer to work! 2. Bugs. 3. Users should not be signed out unless they click the sign-out button. If I can afford to, I will also pay for someone to make my site (at least) as interactive as Freelancer or FB IE usernames and wrong passwords are detected as they are typed, etc
