Niche (AS)

What do you think about my niche for my life coaching business: divorced single moms between 30-40 yo who plan to start dating or who are already dating, but meeting all the wrong guys. I am helping them figure out why they keep meeting the wrong men and what needs to be done to meet the one. How: become the person they want to meet, i.e. if they want to meet an authentic, generous, kind, thoughtful man they want to become that person first. Thoughts?
