Of course it's a bit of a lottery but I've hired 4 guys who had no reviews but were offering what I was looking for & had recent pics. 2 had no face pics but willingly forwarded them on enquiry. I'm happy to say I had a great time with all of them & was pleased to be able to post glowing reviews which they thoroughly deserved. As you say they all have to start somewhere.
I guess it's a case of 'you pays her money & takes yer choice.'
