UK board member here.

I've used GW within the last week.

One word: Brilliant!

Worth the payment - look at it more of an investment, than as a cost.

I've used GW since a change in personal circumstances affected my (planned) studies, and caused me to need external assistance to complete some research/work.

GW have been polite, delivered on-time, and asked/answered the right queries, before any work was completed.
