There is nothing wrong with running a small business and keeping it small. If your business is what you want it to be, where you are managing it and doing jobs that is ok. If you want to grow, at some point you will have to hire more and more. It is inevitable. However, both are ok. It's ok to turn down bigger jobs if you are not ready for them or don't want to take on more risk of hiring more help. Sounds like you are doing a great job!!
I have owned a contracting company for 16 years and have found it more profitable to stick to smaller jobs. Fewer headaches and usually a faster turn around as long as you can keep the schedule full
