All the proceeds from my painting go to SSAFA.  I charge £180 for the painting itself, plus any specific printing costs and p&p - unless you wish to have the printing done yourself.

https://www.photobox.co.uk/shop/wall-decor will give some idea of what is available, and the cost.

For £180, I can send you a giclee printed on 210 x 297mm watercolour paper, specifically produced for giclee printing, along with a high resolution copy in .jpg format, so that you can have it printed as many times as you wish, and in other ways if you wish (mugs, T-shirts etc)

All I need is a suitable, fairly high definition photo to work from (I can't paint what I can't see - particularly when it comes to uniforms and portraits).  A selection of photographs is therefore preferable.  You could send me a photograph, so that I can decide if it is something I can attempt (no commitment).
