Customer Shipping to store

Setting up a custom store where the client offers shoe repairs. The customer sends the shoes to him he repairs them and sends them back to the customer.

To make it easier on customers he wants to provide round trip shipping as in

1) Customer selects shoe type and repair needed
2) Completes the order paying by credit card
3) Prints label on confirmation page
4) Ships using pre-paid shipping to store for repairs
5) Shoes are received and repaired
6) Shoes are returned to customer

Everything is working fine, setting up return shipping and all that no problem. Finding a solution for customer sending to store though.

This is my last attempt at trying to find a plugin or custom method for customers to ship items to the store for repairs. Printing the label I can do if need be using dompdf or something. But I can’t seem to find anything on creating custom shipping for customer to store.

Any suggestions much appreciated
