You would have to look at the "invasive specie" listing for each state you intended to ship to as peppers have seeds. Also different states have different rules as to what can be brought in.
Coming into Oregon from Washington on I-82 there is a sign stating a prohibition on bringing fruit and vegetables across the border into Oregon (this was done to try and stop some of the parasites that harm fruit and vegetable production).
That said I think you could do a facebook posting in a buy/sell page for your local area.
