Hello,
Sir i can Very Easily rank you nº1 for this keyword.
I have over 7 years of experience in SEO and i've ranked for much more competitive keywords, i will build you a 5 Tier Pyramid with WAY more diversity of links than you requested (if you only use those kind of links you will be penalized eventually) with incredible quality, i can send you the details, and after order completion i WILL send you the report of the backlinks created.
Besides i have my own high pr Private network, and have never suffered from any google updates or anything like that, now the same i can't say from the other bidders, you should also consider that outsourcing this to india means a lot of trouble and problems ahead of you... trust me i've dealt with them...
if you are interested on knowing the structure of the pyramid let me know, i'll be glad to show it to you ;)
Check my profile and see my Experience as well as one of my businesses.
Best Regards!
