NO MONTHLY BASIS - SEO Paid per Performance -- 2

Attention: Your project will be considered only if your proposition starts with "I accept to work in a pay per performance instead of monthly basis" The remuneration is by keyword that reaches first page, not by month. I have 3 websites, all over 50DA. I need each one of them to rank first page in Google for 5 different keywords each. All Keywords are 2 or 3 term keywords. Of the 15 keywords, 13 are EASY TO RANK (Score less than 35 at Moz) Keywords are 2 are MEDIUM TO RANK (score between 35 and 50 at Moz). After 30 days, we will check the ranking of the keywords, and for each keyword that reached first page, I will pay X dollars. So if after 1 month 8 keywords reached, the remuneration is 8*X dollars. If all of 15 reached first page, it is 15*X dollars. Every candidate that apply must send me his proposal for how much he would like to receive per keyword that reach 1st place (the X value) I AM NOT INTERESTED IN MONTHLY BASIS SEO. Only in those terms above.
