It would not be T & M if the owner provided materials. More like T & BS. You think you are going to be provided with the right material? Most likely the cheapest quality. Are you going to wait while he gets the right thing? Will you provide your own misc. material instead of waiting for the owner? I would figure the time to do the job and hike up your rate 1.5 or 2 times. Just give him a total price. Then walk away.
