The project will involve the SEO of an offers site called GOSO (see [url removed, login to view]).
I've had many bad experiences with SEO ($1,000s of dollars spent, zero traffic gained). Therefore payment would only be based on success with no payment upfront.
I think the fairest way would me paying upto $0.005 per click gained (this is cheaper than I can get elsewhere but still worthwhile for a programmer). If you could achieve 10,000 clicks a day (at $0.005), this would be worth $18,250 per year.
Please bid per 10,000 clicks gained (e.g. $0.005 = $50, this is the maximum I'm prepared to pay). Payment would be sent each month based on stats, escrows could be used if necessary.
I'm also interested to hear from anybody who could bring in quality traffic at a similar rate to $0.005 per click.
