The first step can be scary, but ifyou do your due diligence, the stress is quite less. You should sit down and at the min. write a plan for yourself..salary, costs, 1-3-5 yr. projections, etc. Have a mission statement, how will you work within the community- support your community, etc.?
How will you reach your market and how will you sustain it? Why is there not detailing there now? Sometimes there isn't a market to sustain it full time. Sometimes it just hasn't been "hit" yet.
Too many guys start out very excited with customers on the weekends and don't do their homework correctly and end up quitting or shutting down after a short period of time. You don't want to turn work away- that's lost money. So if you do this full time, how will you be able to keep up? Employees? 2 detail units? etc.
Just some very beginning questions before you make such a big decision. There are some great books out there at the library about marketing, sales, and so on. Hit the business section and see what you can find. Many are filled with very real ideas.
