Not to discourage or anything but I think the project will not be successful. Fiat is one thing, but this scheme with bitcoins? I don't think so.
Btw, if you are looking for a developer team look at the service section. There are lots there who is offering their service. But be more specific to what kind of coding you need to be done. You can edit your OP to make things more clearer for everyone to notice.
Thank you for you input. May I respectfully ask you, why or what is the reason you think it will not work?
Example:
Say I create a auction for 100 BTC ending in 48 hrs. You thing nobody will bid on that? please elaborate. Thanks
Maria.
