My wife is a trained artist. She works in pencil, watercolour and acrylic paint. This painting of a Benelli was done using high quality Daler Rowney and Winsor & Newton acrylic paints on art card. The picture is A3 size (approx. 420x297mm / 16.5x11.7"). A painting similar to the Benelli would be £120, posted.

Detail close-up:

She prefers to paint in a 'loose' style rather than 'photo-realistic'. All her work is done by hand - she doesn't use any of the tracing techniques that some artists do. She can work from photographs. For commissions, she emails photo updates of the work at various stages of completion so that the client can make suggestions or alterations if required. There is no payment until the work is completed and the client is happy with the work.
There are some more examples of her motorcycle work here:
