Hi! I am desperate! I need this fixed ASAP!

Situation:

i own a an auction website...this is a penny acution, in this website there are on auction hot items such as iPhones, iMacs, TVs, videogames etc...this is how it works...Users buy a bunch of bids, they cost 50 cents each, and every time that a bid is placed, the price of the item increases of 1 cent and adds 10 seconds to the end of the auction, the items have NO minimum price...

Problem:

....Everything was running well till yesterday, since yesterday the script started acting up...it will make the auction end as soon as an user reaches about 200 bids placed, using the bidbutler or not! NO MATTER WHAT! I have setup to do not make the auction end untill the item reaches a minimum price...but the script IGNORES this setting now! I REALLY REALL REALLY REALLY need this to be fixed asap! Today i sold an iPhone for $ 64, an iMac for $ 69 and a Sony Bravia 52" for $ 86!!! And i don't even want to mention the other items! I have to ship these items and i cannot take the website down or claim "technical issues" because it'll mean BAD REVIEWS, so losing customers and business, and i am VERY precise about my business! And the night is coming, the users will reach that target quicker, because of the low traffic!

The website is made in PHP, so you must know about it! Willing to pay whatever! Just tell me a price! today i lost over 4K between last night and today giving away all these items for such a low prices!

Also i have some other minor bug to fix, but that will be later, i need to fix this first, also i will need to RENEW the template/Graphic! Or maybe get a new template. I am willing to get one or more freelancer to do all this...If you want to see the website before to bid...it's myluckybids com i don't know if i can mention it here, but i really need help FAST! Thanks!
