You can only ask.

I trade all the time with clients with skills I can use. One has a landscaping company and invests in rental properties. I survey for him in exchange for landscaping, fertilizing and tree trimming.

I just swapped some work with a guy that does hurricane insurance mitigation, he inspected my house in exchange for a task on house he is building.

It can't hurt to ask, throw the idea out there and see if he is game, you might get a response that he is too busy or you might find out he is more than willing to do it. If your worried about insulting him don't be its common for people to barter trades.
