One other thing if you plan to have employees is to be familiar with the "workman's comp" laws in your state. I have a business where I had employees as well as utlilizing the services of many many IC's supplementing the work of employees.
In my state, NY, where the owner of a business is the only worker, YOU ARE EXEMPT from workman's comp. But so long as you have ONE employee, you have to go out and get a WC policy. If your assistant got into an accident as an employee, driving to see a wedding say, not only would YOU be responsible for paying hospital bills (covered under WC) for his or her injuries, but everyone else he or she hits.
It gets better.
When I started using IC's, I didn't know the intricacies of WC, and under my workman's comp policy, when they audit me, I'm reponsible for, and get CHARGED for IC's that does not have WC, or is NOT exempt from it. Here in NY State, I can hire an IC, but in order for him to be exempt from WC (so I wont get charged) , he has to set himself up as a business, could even be a proprietorshhip, but doing so would get him a WC exemption if he is the only employee, and that gets you off the hook. The first year I had my WC audit, I had to call around my IC's and get their WC policy numbers. I was surprised (I shouldn't be, but I was stupid) many didn't have WC policies, and I was CHARGED for those that didn't carry WC. In other words, I'm paying for THEIR WC.
If you are not aware of any of this, you'll get yourself in trouble coming and going.
Now, if it is the SECOND job for these people, it is EVEN more important you set things up right. I don't think their PRIMARY employer would appreciate their employees getting hurt on their SECOND job, collecting disability benefits, medical, and so forth on the first employer, and you get off scott free. No way.
