Kodak Printer Round 2

Well we've printed about 30 copies on my printer and all seems to be going  well.  Finally ran out of color ink but at $15.00 a cartridge that isn't bad.    Talked with World Vision about the use of their name.   Very interesting conversation but turns out that I can say that I'm a strong supporter of World Vision and that any profits are going to be used to help bring clean water to impoverished areas of the world.   Finally got a quote from a local printer and it comes down to about $5.20 per book.   Not bad.  Much better than Lulu but still quite a bit more than doing it myself.  Hmmmmmm.......   What to do???     If I go with the $5.20 price I need to order 500 and hope I sell them all.   I'd be done with the printing part but would have to step up the promotional aspect.  If I print them myself 1 hour of every night is given over to printing and cutting but then more money goes to clean water and I only have to print what I think I'll need.  Hmmmmmmmmm....   Must Pray!!
