I appreciate that you may not want to pass your valuable items to a complete stranger who is then going to start messing about with them so I have devised a few alternatives.

1/      On selected items I would be willing to buy from you at an agreed price then re-sell back to you on satisfactory completion of the restoration, therefore alleviating you of all risk.

2/       On selected items I would be willing to purchase outright if you feel you do not want to restore.
