Only employ as many people as you need, without putting too much work load on little employees.
What I mean is, don't cut down just to save money if it will make the employees you keep have unbearable amount of work to do.
You must find a balance, but if you have around 300-400 clients / month and 12 employees, you should be fine with that amount considering regulars typically pay the same every week.
Also I did some math, and at 350 gigs / month with 12 employees, it averages out to one place / day per employee. That is very manageable where you are at today.
