Search on AW in a more local area than East London/Essex.
Find a prossie who floats your boat (use the tick boxes to narrow the list down), copy her 7 digit AW number and paste it in to the search box in the top right hand corner of UKP, and see if shes been reviewed or talked about.
Have a search on here for 'east london' and 'essex' etc, and take a look in the reviews section. There are two good prossies in the region but they aren't working next week, Maggie21 and Michelle Independent. I have them on my to do list.
Happy punting.
