UK private MtF hormone prescriptions

[lindsay40k.livejournal.com]

What sort of price range is likely for a trustworthy supply?

EDIT:

Also, is it an idea to get a private diagnosis to open the option for NHS prescription without waiting years for the diagnosis?

Myself and the friend (who is the one considering this route) are unemployed northerners with little in the way of local NHS resources to rely on :/
