There's a big market here.
Some folks do nothing but deal - they never rear any insects on their own.
You don't have to raise any livestock either in order to make money, if that's what you wish. As noted before, you don't have to bother with any equipment except what you may want to keep handy in your garage to hold over some live inventory for larger profit and faster shipment. The people already in this business are doing okay. They must be because you hardly ever see them advertising for new business. Most businessmen would give their eye teeth for a deal like this.
