I would tell you that before you actually pulled the trigger that you need to sit down and factor all aspects of the business plan and every possible contingencies. For example:
1) What do I do if my business takes off like a rocket? Employees? etc....
2) What do I do if I have a seasonal slow down? How do I continue paying the liabilities etc...
3) What is my 1 year & 5 year plan as to the types of services I will offer.... or will I continue being mobile vs. shop base?
4) What is my current marketing/advertising plan?
5) How does one business model benefit me in tax deductions over another model?
There are tons of questions like that. It is a daunting task and one that makes you rethink your position often, but one that is better done now then to be discouraged by having to rough trough those life situation later.
