i employ and have done since day 1.
i'd suggest you should do some planning and goal setting for where you want to be in 10 years time, then work it back to 5 years, 3 years, and 1 year.
there are advantages to employing and advantages to being a one man band.
there are examples of people doing each on this forum very happily
i would imagine that if you drift into employing just because you are growing then that is probably not the best way to do it.
you want to have a think about where you are aiming for and why.
include in your goals what sort of lifestyle you would like, what sort of income you need, where you want to live, what sort of holidays you want. really give it a few weeks to think it through and imagine your future life.
when you have a clear idea where you want to be, you will be able to make decisions like how you want the business to develop and whether than includes employing or something else.
