I'm looking to start an online business designing products for print and promotional products. Basically anything from business cards to T-shirts, pretty much anything a person needs their logo or business info printed on...I want to offer it for low affordable prices. The thing is I want this to not only be an online business, but I would like to also take my business to swap meets, fairs, etc. Any advice on where to buy equipment, names of some reliable vendors, and also do you recommend "shopping cart" or "paypal" links to manage payment transactions online? What has your experience been...good or bad? Thanks for any and all help.
