Writers Market and joining a group that supports poetry sales/publishing leads like Upwork, the genre's top freelancing site could be very successful for you. I have freelanced poetry for weddings, baby christenings, funeral service programs, anniversaries, etc. for over 40 years. It is one of the most gratifying writing experiences I have had in my writing career. Try to build up a following by doing a Live reading perhaps once a week, same time, same station. If you get only a few followers at first, stay at it. Poetry lovers historically congregate and inspire each other. Get that first small poetry handbook self published and put it up for sale in your website. To have a wife who gets out front to promote your poetry is already a win win. Wifey, help your husband build his "brand" of personalized poetry. During these troubled times, poetry is a cushion of comfort and closeness.
