Of course you do!
To help freelancers like you and me, I've developed a great script to aid designers in selling their templates/graphics/scripts or basically anything.
MyFreelanceAuction is a simple script developed entirely for freelance web designers. The script has simple features which allow a web designer to make his own auction and receive bids. With each bid a public running total will be updated for potential buyers to keep an eye on. The designer will also be presented with a private online page with the details of each bid, the bidders email address, bid amount and the option to delete that bid. Once a designer chooses to end an auction, he can simply send an email to the email address of the highest bidder to ask for payment.

Thankyou for your time,
