Ithaca 37 restoration possible?

Hello:

A close friend recently lost his father. A few weeks later his mother handed him a worn old zippered case that contained a rusted Ithaca Model 37 12 gauge that had belonged to his dad. It likely hasn't seen fresh air in at least 40 years.

My friend is an active waterfowler and occasional upland hunter but doesn't really know the various avenues to explore trying to make this gun functional and attractive again. So here I am.

He is interested in making it look nice again, perhaps even to hang in his office. Functional would be a bonus. The action is very sticky but does cycle.

Any thoughts on who to send it to that could deal with the rust (with the understanding of course that pitting can't be dealt with), do a nice reblue, and refinish the wood? On top of that, who could tear it down and do a complete cleaning and so on?

I grew up using one of these in 20 gauge for upland hunting but am not comfortable tearing one down.

My sense is having this restoration done as right as possible is more important than price considerations.

Thanks in advance!
