Sales and Leads

I have two projects. 1. I am launching a paid membership site where people can sign up for access to an online shopping hub. All of the coupon codes, dining deals, airline and hotels, rental cars, grocery coupons, product deals, and more. I am probably going to price it somewhere between $4.99/mo and $7.99/mo. I want to know if you would be able to drive paid sign ups and how much it will cost per signup? how long delivery takes? 2. Is just CPA offers. I have several cpa offers from neverblue that I would like to promote. they are all free to sign up. No cc. Some are long form 1 page and some are 2 pages. How much will your service cost per lead? and how long does it take?
