I know this is mainly an online site, but I have an idea for an offline, service-based business and I was wondering if there's anyone who knows where I can go to get some advice on how much money/capital is needed to start this business and most important, whether there is a need for this business.

I know that for online businesses and information marketing, they always say to make sure there is a growing need/demand and I want to make sure there is a growing demand (and the costs involved) before I go forth in this business.

Although I do plan to have a website, the actual service itself is done offline (it would be kind of hard to do this online).
