"Name your price", "Make offer" plug-ins?

I need to be able to have customers make an offer on a particular brand of product on my site. If the offer is acceptible the price would show in the cart once the product is offered.

I've only been able to find one plugin, but the developer apparently isn't around. I paid, but didn't receive any files.

Does anyone know of a plug-in that will do this?

Thanks for any reply

There is no exact extension for this but here is a one that is pretty close to what you are looking for, You can also contact the developer to make some minor tweaking and get them implemented in no-time with least cost.

This extension Allows customers to bargain and offer their price. The price by admin is display along with offered price field to let customer input their price. If the price is within the defined limits the customer will be able to checkout and if not he will be required to enter a higher price.
