Google Ranking and Unique Traffic

I'm a web developer and have dozens of sites but I'm completely inexperienced with marketing/ranking the sites. I'm looking for a realistic price on what it would cost me to rank several keywords on all major search engines:

mobile phone credit card processing
mobile credit card processing equipment
cell phone credit card processing
mobile merchant credit card processing
mobile credit card processing
phone credit card processing
iphone credit card processing

Please let me know the plan of how you will do this (backlinks, social media, PR, etc), estimated monthly hits, etc.

*NOTE: Please DO NOT only reply with your program "1000 high PR backlinks for only $100" as that means nothing to me. I'm looking for a marketer who can GUARANTEE placement with longevity and has a clear plan of action. THANKS!!
