Adult site promotion and SEO optimization

Hi, I am looking for a marketing partner that can drive adult male traffic to an Indian adult website. SEO and inbound links heavily needed. Currently the website has page rank 1. So, need to improve the page rank and should come in google first page for many keywords(in order to improve income). The site has only 3 to 4 pages. I Am willing to pay one-time fee, monthly fee, percentage of sales, or a combination of all three. Long term partnership desired, but must be able to deliver results. It is an Indian adult site. I can let you know the main keywords that customers look for through PB. Let me know your thoughts..
