How to exit a successful but boring Etsy business ($300K/year)? Need strategy

I run 3 Etsy shops that have grown to almost $300K in annual sales with a 35% profit margin. Despite the financial success, I'm completely bored with the business and want to move on to other projects. Here's my situation:

• 3 established Etsy shops selling [personalized art/digital products]
• Almost $300K in annual sales with 35% profit margin
• I've grown tired of the day-to-day operations and want to focus elsewhere
• Tried hiring someone to run it (an "operator"), but they lack experience in some key areas (marketing, strong English skills, business confidence)
• I'm still spending significant mental energy on the business despite attempts to step back
• According to my knowledge of Etsy TOS, I'm not allowed to sell the shops outright

What are my realistic options for someone with a business at this scale? Has anyone successfully exited an Etsy business while maintaining the income? Should I keep trying to find a better operator, even if it costs more? Could I restructure into a new business entity that could be sold? Or just accept that I need to be involved and find ways to minimize the time commitment?

Any advice from those who've been in similar situations would be greatly appreciated.

UPDATE. To clarify: The 35% profit margin currently functions as my personal income from the business. I'm looking for solutions that would maintain most of this income stream while freeing me from daily operations.
