My bid is for .50 per link, since you asked for a "per link" price, although I would much rather work on an hourly/per month basis.
I would only require $5 per hour spent obtaining links, since it's not complicated work- just time consuming. I would give approximately 40 hours per month, for a total of $200 a month.
If you prefer to work on a per link basis- the software you use must effectively track how many links you are getting so that it is fair to both of us- and as I said, I would go with .50 cents per link.
I can provide client references.
Thank you for the opportunity to bid,
Debbie Dragon
