How do I go about pricing my tattoo flash art to sell?

Anyone have an idea to go about pricing "flash art" for tattooing? I've drawn many single pieces as well as full sheets.

Keep in mind the:
Size- Ranging small to very large
Color or Black and White
Simple to detailed.

Any information would be great.

Thanks

How do you sell your tattoo art?

I know that in the artist's world...It is very hard to make money. But I'm not really looking for a job, but mostly some pocket change.

I draw portraits and tattoos. I've sold 8 or 9 portraits and 2 tattoos.

I guess my question is how would I sell my tattoo art to a parlor? Or should I just stick to selling them to the person wanting it done, like Ihave been doing?

I fell in love with portraits when I drew my first one. I draw soldier portraits mostly for me friends, but I'd really like to sell my work. I donno...Just a thought I guess.
