Man that is a tough question with a lot of maybes, good luck, and other stuff I have not thought of.
Most of the time a Rep will really want it after a demand has been established and that is another "Ball of Wax". That demand is a big chain in what one of them can do as it starts with the consumer and works its way up .. Retailer, Wholesaler (Distributor) and the Rep is doing the sales leg work for you within this chain. The "Web" being another factor that I have noticed to help create this demand and you can supply some of the items that the "Chain" has not yet added to their stock. I know I have not directly answered your question but that "String" is hard to "Guesstimate" ... Hope this might help a little.
