why don't you work out the numbers v roughly.
I paint for a hobby.
I could possibly complete a painting a day (pushing it)
Cost of canvas board 12 pounds,
cost of paint, cleaner, brushes, varnish, fast dryer etc I'd guess, if one pic a day, 15 pounds a week so 2.50 a day.
Frame - if made 65 pounds
If cheap from The Range 15 pounds
Wrapping 2
Delivery 8
? petrol to go to buy things, take to post office, averages 4 pounds daily (would keep receipts for tax man)
Extra heating - none as I'm home anyway
Ebay costs a day 50p (guessing)
Total costs per day 44 for cheap frame and 94 for good one
I could sell for 80 the ones in cheap frame or 250 for good frame (am amateur artist so won't try for mega bucks initially)
Say I do 3 in cheap frames and 2 in dear frames a week - that would make me once sold possibly 320 week in costs. Possibly 740 in sales (3x80 +2x250).
Profit 420 a week if all pictures sold.
If I sold the pictures for 250 (cheap frames) and 2,000 properly framed I'd make 4,750 in sales, of which 4,430 would be profit. So 4,430 a week, about 17,720 a month.
Hmmmmm. Now I see why the prices of art are so high. You're unlikely to sell all your pics and you need a good profit on each one you do sell.
