SEO work for my BDSM Sex toy webshop

DISCLAIMER: this is BDSM sex toy webshop - NTSF18+
Do NOT apply if it is problem for you for whatever reason.

My site: hotsteeltoys.com

1. Detailed Page analysis and suggetions for site improvment (ON-PAGE work), I need more serious than just copy-pasting SERP report.
2. I have 15-25 keywords, I also want keyword suggestions after competitor analysis (eg. fancysteel.com)
3. Regular OFF-PAGE work (link building, book marking, etc.), utilizing the latest "Google leak" information
4. Result oriented aproach is needed: I want to see siginficant improvement within 3 month time, in order to continue.
5. Regular, transparent reporting is expected every 3-4 times a month. Project is paid on monthly bases.

The keywords I used to target:

deep throat training
deepthroat trainer
nipple stretchers
pet play bondage
pussy clamp
spiked chastity cage
Humbler
Breast Press
Breast Press With Spikes
Pa Chastity
Anal Hook
Anal Bondage
Pear Of Anguish

I used to have first page ranking for some of these, but am willing to change some of them if I get good suggestions.

I have strictly limited monthly budget. Who gives the best value for my buck, wins the contract.
