Thanks for the response- seriously-I know it sounds dodgy- but it's not something I can afford to do professionally and all I was looking for was someone with more knowledge than me to cast an eye on a report and see that it was sound in content- not on the subject- but on the methodology and presentation.
For all I know they could write a load of stuff that sounds good but worthless from an evidential point of view. I don't want anyone to take sides. I do understand completely where you are coming from.
