Hi,
Well, site like ebay is quite popular for an auction site and I am a big fan of a crowdfunding site like Kickstarter. Since auction site consists of lot of lot of features, before finalizing the deal I would like to have a conversation with you.
I would request you to open up a line of communication so that we can discuss further about the project over Skype , phone or chat box.
Looking forward to hear more from you.
Thanks
Neel
