to start - we found the SBTDC: the small business and technology center. it focuses on North Carolina but i'm sure there must be resources like it in other states. once we've got a strong outline of our business plan - we have every intention of taking it by their office for a consultation. they also offer different types of courses and training series. a particularly interesting one for us so far is about business plans! ...the best resource so far has proven to be a really awesome start-up guide!
we've also been utilizing the BizPlanIt.com site that provides a free virtual business plan guide. i just tried to access the site and for some reason it's not coming up for me. if you're interested, i've already downloaded the virtual business plan and would be happy to share upon request! it's also found on facebook.
if you're starting a business plan or if you're just updating it, these are great! if you're working without one - there are a lot of resources that highly suggest them. if anything, it'll help you think through everything you're doing.
