A magazine that I was reading the other day featured a list of cheap (and in some cases free) online tools to start your business :

www.emachineshop.com (light manufacturing)
cafepress.com (e-commerce, promotion)
associate-o-matic.com (online retail store)
mturk.com (market research)
openoffice.org (microsoft office)
pad2pad.com (custom circuit board)
salesforce.com (CRM software…we use this, it’s great!)
