Hi
I may be missing something here, but to me it seems obvious you should be offering your
seo skills to help to people in the hip hop business who have websites but don't know how to promote them. In other words offering niche
seo work in an industry you understand. You could focus on the 'small guys' who are passionate about what they do and need the traffic but don't know how to optimise their sites. In that way you are killing several birds with one stone - helping people you like and respect, using your
seo skills and working in an industry you are passionate about.
Best wishes
Fiona
