The church to which I belong (in Wisconsin) has a large event annually as a fundraiser, which includes a silent auction. This year we have a piece of fine art donated by a member, and we'd like to solicit bids from members of other churchs in our diocese. This would include churches in other states. Since we have our own website, we'd handle all of the bidding process internally. Are there any regulations on this type of thing, other than fraud regulations? Are there any interstate commerce or licensing issues we have to worry about? Please advise. Thanks!
