They pretty much summed it all up. When I went to school they told me that i would be on a 12 week fast track! tHEY SAID i WOULD BE OFF AND RUNNING!
I would go to sba.org or find a business plan to complete. Many of my friends said that htey wish they would have. Find insurance, website completion, messing with software can be really time consuming so take your time and relax. I purchased AHIT checkbox style and I have had some problems, also too many boxes for my clients liking. I do believe though that if you are new it is probably the best to makesure you don't forget anything. There people are some of the nicest out there. I am presently trying e-Inspections software that they will customize for you.
Aside from that I am focusing on getting other certifications to be able to offer more services to my clients. Marketing in our area is one on one. Beat the street and don't stop meeting people, carry cards everywhere. Target offices and go frequently. No one likes to hire someone they don't know. Also, your less likely to be ina lawsuit with people who know and like you.
Good luck!
