I fly from the same airfield as Westflight and have heard about them. The man behind it is Chris Brooks, he's dedicated and determined to provide a value for money package and not appear to fleece you like some unmentionable places.
Their package seems to be very well organised and structured to give you quality time in the air, a thing that potential employers would be pleased to hear I'm sure.
Give them a call on 01452 857775 and get them to send you a brochure.
And as for Gloucester airport, imho it's the best GA airfield in the country.
