Hi Haoleb,
First I want to say hi. It's been a while since we talked and when I first read this post, I didn't realize who it was.
I think Dan from ModWright had many good points. One of the key aspects to consider is developing a reputation with your customer base. No matter how good or affordable your products are, your business ethics will be the more important than anything else. If you treat your customers well, stand behind your products and have some knowledge of the products you represent, you should be able make it through the ranks.
There will be good times and bad times but any business will go through this. I have been lucky enough to have supporting wife for those long hour days.
Borrow as little money as possible. When I started, I had a full time job so I did not have to rely on Response Audio to support my family of 6. My wife also has a decent job. I was able to get to the point of being able to quit my full time job of 17 years and haven't looked back since.
Some have mentioned that no matter what you do, it will become "just a job" in time. Luckily for myself, this has not yet happened. I truly enjoy what I do (most days anyway).
Good luck on your venture. Be smart and take your time.
