I'm a developer as well and I can do this myself but I'd be happier to free up my time for other things. Here's the site I've developed so far: http://www.bickmart.com/lab (left the payment integration) My requirements: 1. Make a bid 2. Make the payment straight away after each bid 3. After payment is made, only then is the bid verified. (Else it's not counted) If you're able to integrate Paypal & Google Checkout with the reqs above (preferably someone with experience), please pm me your price and estimated turnaround time (best within 3 days), thanks.
