I have a wholesale costume jewelry company with limited funds. Should I hire a salesperson and, if so, should that person be full-time of part-time?
It sounds like you will also need an additional source of capital to grow faster, so you might want to look at a credit line or a partner. You also may be able to find salespeople who have a good set of contacts to work on commission only upfront.
The key, whatever you do, is to make sure you tighten up your cash-flow gap--or even eliminate it entirely--by working your current business model in a little different way.
All the best.
