It sounds to me like you need to hire an employee. If you don't have enough revenue to support another person, but your company requires the work of two people, you are going to have a bad time.

The hard part about having your own business is that you have to figure out if your work/income ratio is appropriate... if you have to do the work of three people just to make what you would as an employee of someone else, you might need a new business model or it might be time to be an employee.
