If your going to take the risk of running a business either full or part time. Make it worth it. For you new solo guys. Remember you get paid twice. First your paid as the worker this should be a set rate. I use an hourly rate for myself. This rate is paid just like if you had an employee do the work. Then you get paid as the owner. That is if you priced the job correctly and there is money left after paying the employee and overhead cost.
