Definitely shop for insurance.
Here is what I can say from having done 10 years ago, what you are about to do now /forums/images/graemlins/crazy.gif
Start slow, but be aggressive in searching out small easy jobs to learn on. You might have to really discount your initial bids to get some of these jobs. What is important is that you do a good job and others are able to make note of it, this is where you build your "word of mouth" reputation. Some examples that worked for me;
1. lawn cutting
2. snow removal
3. lawn care
4. garden tilling
5. field mowing.
6. pad installation for garden sheds.
7. small lip-lock retaining walls
Backhoe work and FEL work can become a problem for you if you are not careful. Always remember to "call before digging" so you don't dig up something you are not supposed to. Also, remember this; people are not perfect and you may discover something like a gas line where they said it wouldn't be. Sooo, go slow, look and listen. /forums/images/graemlins/grin.gif
At some point you will need to get something for "dumping" Maybe up front you could buy a dump trailer to haul and carry with. There are pros and cons to this approach but, if you don't have the $$$ for a dump truck, you can make this work, I did. /forums/images/graemlins/tongue.gif Now I use an F-650 dump, but I still use my 10,000# E-Z dump trailer frequntly.
The other avenue to explore is tax time benefits. Check into this with an account or do some internet research.
