It would be best possibly to join a few networks. They all have a few survey offers where some may have a few more than others. If you need a list of Affiliate Networks, then heres a large list of some of the best. Good luck with this new site of yours, hope it works out well for you.
Yup you should definitely join at least a couple of networks - each will have their strong offers, which will suit your requirements
That is a useful link John. I've noticed that we are on your list. PrimeQ is a network which pretty much specialises in surveys - we've got loads of them. Feel free to contact me at ndixit AT primeq.com if I can help in any way
Again, we have a good collection of surveys available on a CPA basis. We only promote campaigns that meet a certain performance threshold so you can be sure they convert!
