What ways might you suggest that I can get in front of my niche to offer my services?

Hello, I’m trying to understand what might be the best ways to target affluent attorneys, doctors and CEO’s for my services. The most valuable commodity that this group has is probably their time so it’s been difficult trying to get them to meet with me. I offer them a wardrobe service that comes directly to them which saves them time. But the hardest thing is getting them to give me 15 minutes to introduce my services. Any thoughts on the best way to get in to see them?
