I'm Barney Douglas, professional commercial photographer with extensive musician experience from rock bands to classical. I have my own studio in West Sussex, and without knowing your precise location I really don't know if I can help.
But, unlike all the other bidders so far, I'm UK based ... and a photographer, with my own studio, and full professional commercial insurance.
Your budget is, I'm sorry to say, somewhat inadequate, but assuming you can make it to my studio, the £100 will get you a one hour shoot in the studio and at a nearby location, proofs (overnight) and up to a dozen fully edited images. in digital format.
That's probably not what you were hoping for, but by UK standards it is a very competitive offer.
Please message me.
