Have you noticed any dirt piled up or any signs of digging that can help confirm whether you have groundhogs burrowing under your deck?
MSU Extension cannot make a recommendation about a company that can live trap and remove the animal. If you choose to trap yourself, try baiting with apple. But then you would have to decide how to kill the animal, whether by taking it somewhere else where it will probably die slowly, or by killing it outright. If you get an extermination company, that is what they do. They set a trap near the opening they think the animal is using to enter and exit, then take the animal away to dispose of it.
This is also a good article with more information about woodchucks that you might find helpful, including guidance on exclusionary measures:
