Encase two rose heads in resin

It's a small job. I just need two long-since dried out rose heads encased in resin cubes. The rest of the bouquet has withered away, and I'm hoping to preserve these last two before it's too late. They are certainly dried up and delicate. I would like them put into separate resin cubes for decorative display. I don't have access to a ventilated work space or else I might try to learn it myself. The rose heads are small enough, just a couple of inches. The cubes don't need to be especially big, whatever you think it a good amount of space in your expert opinion to maximize quality and displayability.

I should mention, I am in the Boston area. I'd prefer not to do anything by mail since the flowers are so delicate right now , so ideally I'm looking for someone local. If need be I can drive into neighboring states, but that's about as far as I'd want to go.
