Hard to recommend and indy without any preferences but any of the advertisers on here are all reputable and well reviewed.
If you want to use and agency,you almost can't go wrong with anyone at SVIPs.
CCE has some nice ones as well but it's hit and miss.Lauren,Nya,Saija,and Ariel have all had good reviews on here,the rest you'd probably want to 411 first.
SU tends to have mostly average looking SPs with lots of restrictions.Ok if you're looking for a safe,no frills shag but GFE's are few and far between there.
