If you buy them from Harley they'll cost you an arm and a leg!!
Do you want to make money off these parts or are you trying to gain experience??
The reason I ask is there are easier ways to get free parts!!
Go to your local bike shop and introduce yourself as a beginer custom painter and that you'd like to paint some flames on one of there bikes or parts on the wall - take some samples of stuff you've painted if you can - ie: Mailbox, trashcan...
The idea here is to get your foot in the door. If you can stike a deal like you'll paint it and pay for your costs if when they sell it you get a predetermined price you'll only be out of pocket for the paint until it sells. OR - Ask them to only pay for the materials and mark your materials up a bit - say it costs you 250 - then charge 350 -- to them it's still a deal!! --- Thats the way I got started 6 years ago - give a little away and people will spread the word. then build your reputation bfore your prices go up. I actually stopped painting for a year and a half and when I jumped back in It was easy -- You'd be suprised how fast the word gets out among the bike community --- Do the best work you can and always try to do a little more than what the customer asked for -- I did a sporty tank and the guy just wanted the the sides done - I did the sides but also did the top of the tank with the same basic design - it took me and extar hour of time and when the customer picked it up he was ecstatic and actually tried to give me a 100.00 tip -- did I take it?? Nope - It would be worth more top me in the "spreading of the word" than to take it -- now anytime anybody asks this guy about his paint he says "Bones did it and he even threw in the top for free, I tried to give some extra cash, but he wouldn't take it"
