Sales Agent on Commission-Garden Centre Sector

We are a new company manufacturing logs from straw. We have had significant success selling into garden centres in the Midlands area but existing team is concentrating on manufacturing and refining product and has too little time to travel. We are interested in anyone who will sell on commission, idealy in the Midlands area, but would aslo be interested in anyone who has good contacts outside of this. Please quote your requirements in regard to delivery and commission.
