Small business owner. (Oil Field supplies) I calculate strokes per minute on pump jacks, and sell the belts and pulleys for them. I also specialize in hydraulic hoses, industrial hoses, air hoses, sandblasting hoses, airbrake hoses...well basically any type of hose. Safety supplies, (H2S monitors, gloves for whatever material handling is involved, safety glasses, cleaners, penetrants, flagging, wheel chocks, safety chains, tagging, hearing protection, harnesses, hard hats, safety vests, and MSDS documentation. As such I am bookkeeping, accounting, inventory management, the help, secretary, and the final blame when something goes wrong.
Am I the best at what I do?
Customers will call me to do all the calculations and bitch work and then purchase at my competitors (larger suppliers) for a cheaper price.
