Niche – feedback wanted

I am currently in coach training and absolutely love it. I feel so inspired that I came up with a niche for my future business and wanted to get feedback on it.
Women between 35 and 55 that were or will be an expat in the Middle East and who feel stuck and dissatisfied with their life or career.
I did not specify it further as I want to keep my line of work a bit broader. I believe it’s possible, but wanted to hear your thoughts.
