Hello,
We have reviewed your website and, the work is really doable as we have already developed a lot of websites with auction module. I got to know that your website is in PHP but, need to clear about the type of auction you are looking for; is it simple auction or something more like ebay auction module?
Note: We will provide all of the other mentioned services but before proceeding further, we need to have a detailed discussion.
Thank you,
SR
