You should be able to find a rug plant operator willing to work with you in this way. I would make it part of the deal that HE is the party to pick up the rug/s at the customers home or business, and to return them as well. Otherwise you will find yourself frequently wrestling alone with large rugs
that may not even fit into your work vehicle. Let the rug plant people do all the heavy lifting AND the cleaning, and agree to a reasonable referral fee.
