Hey Dean
Well when the new sites our up and running there will be 6 in total and we are going to link to everyone interested from all 6 so it should help some of you guys out.
Not a 100% on the ins and outs of it but the web guys say we have a page ranking now of 4 on google and people like the BBC are 1 so that is not bad going.
We find we get our best work of the net as the people that contact you from it tend to need something sorted ASAP and then you can charge a Premium for the work.
All the best
