czach,

When looking for a wholesaler, ask them for references. If they are intent on doing business with you they will afford you clients numbers. Call them, ask how the wholesalers products are, and if the deliveries are timely. If they are you're on a good path. It will take you a couple of orders before you become comfortable dealing with them, but this happens in any business.

When you have a drop shipper, they are essentially exactly like any other supplier. You receive an order, the money is sent to you, and you call and order the product. I always had an AMEX card ready to order the parts instead of waiting on any type of deposit to complete. Call, place your order, agree on a payment method (I usually have them file my card number under my account) and wait until you receive word from the client that their part has arrived. It's also very important to make sure the drop shipper is quick in supplying a shipping/tracking number to ease the nervousness.

Any other questions let me know.
