Dear Sir,
I have read Project Description & our team already worked on an Auction system, so we do have clear idea about this business domain. Please go ahead and share detailed requirements or list down all the high level features in a document to estimate it precisely, because based on the project description, it is hard for me to give you any estimate.
Please click on the chat button for further discussion about your project, I can then also send you some of our recently developed websites URL.
You may ignore the bid & once requirements are finalized, I will then give you firm bid.
Look forward to hearing from you.
Regards,
YK
