Hiya bud,
Little hint for budget product shoots>
Get a white sheet & some boxes. Place the boxes to create a corner and then drape the white sheet over and you have created a product studio for you photos!

Its your work, I imagine your a fairly hands on geezer if your prepared to dismantle a bike to paint it, so why not have some fun and give it a bash yourself. If you want I can take the shots and do some tidying up in photo shop afterwards.
Obviously your not going to get a motorbike into your bedroom for a product shot, but if you can master it for small things then I'm sure your creative enough to make some kind of contraption/photo area for a bike or car.
Regards
Craig
