I would like to have a directory of companies that have exclusive deals/offers to my site's members (based on vouchers and coupons). So, basically I would have to contact companies and ask them if they are interested in creating a special voucher or coupon and offer it to my site's members.
Are there any companies what I could contract to take care of the negotiation with the companies offering the vouchers/coupons?
What is the best approach to get those offers from the companies? I think that just calling them and asking for a special promotion won't work. But at the same time, I don't see a reason for a big company to not offer $10 or 10% discount to the members of my site, having in mind that, if they use the voucher/coupon, it means they get a new client/sale.
Are there any specifics that I should know of in this kind of partnerships? Any suggestions?
I would like to start with at least 10 offers.
