Would be happy to put you in touch with the Hip Hop people if you want the business - not my thing to be honest and you're more than ideally placed if you don't mind doing work for the competition (a kick back would always be nice if it comes off). I do warn you though there are some initial complications with this one - they initially are in desperate need of a re-design for the existing site (looks ok front end but the backend code is spaghetti) - could do it all on link building and avoid the re-design, but they want re-design anyway. They're also looking for some sort of affiliate marketing system but don't seem to have any clear idea where they are going with this. There are about 20,000 cached pages. Initial
SEO budget may also be an issue, they want the marketing system in place first.
As a project its an awkward one to be honest, but since you have a foot firmly planted both in
SEO and Hip Hop, might be ideal for you.
Let me know if you'd like to have a chat with them and see if there's any potential for you.
