As a fellow small business owner I wish you the best in your ventures. One thing I wanted to suggest that may or may not help your business. Personally, I only like to deal with small businesses that use USPS (Post Office) for most of their shipping. Flat Rate boxes make things cheaper for the buyer, the post office will pick it up just like UPS, and you don't get ripped by high UPS rates. I ship daily and the post office is cheaper 95% of the time over UPS. For example: I mailed a 30 lb. gear box recently. USPS Priority (2-3 day) with confirmation was $16.95. UPS ground (3-4 day) wanted $27.88 for the same + a residential fee and wouldn't drop it off on Saturday. My customer was happy that I saved them a few bucks. Of course what you do is up to you, just my thoughts. Good luck!
