For Starters I suggest:
1. Locate some sources.
2. Research the species sold.
3. If the source raises crayfish in quantity visit the grower.
4. Ask lots of questions.
5. Do more homework.
My main source-supplier harvests his crays by seining. I trap and seem to catch quite a few. ther are special crayfish traps that minimize exiting of the crays.

How to Raise Crayfish in a Farm Pond
By G.K. Bayne From the Internet - The Daily Puppy
Instructions
Things You�ll Need:
�Shallow farm pond.
�Aquatic plants.
�Pond aeration.
�Fish trap.
�Fish bait.
Step 1:
Ensure that your farm pond is at least 18 inches deep. Crayfish prefer shallow water, but need deeper water to grow, molt and breed..
Step 2:
Plant aquatic plants in the pond. This can be done at a shallow end. This gives the crayfish food and areas to hide..
Step 3:
Stock the farm pond with 40 to 60 pounds of crayfish per 1 acre of surface water. Crayfish are cannibalistic and will eat each other during molting periods, so for a decent harvest, more is better than less..
Step 4:
Install a paddle wheel or other type of pond pump to keep the water stirred and oxygenated. Crayfish require the oxygen level in pond water to be at least 3 parts per million (ppm) in order to live..
Step 5:
Add commercial crayfish food to the pond weekly. While crayfish can live exclusively on aquatic plants and other pond food sources, the addition of feed will help the crawdad grow faster..
Step 6:
Harvest the crayfish by submerging a baited fish or minnow trap in the water. Shad, chunks of catfish flesh, or chicken livers make good bait.
