Niche focus

Hi, I’m trying to get specific with my niche:

I help women designers in their 40s shift their career focus to make a ton of money.
I help creative women over 40 who want to shift their career to achieve their money goals.

Is “a ton of money” too vague? I will try this wording out first before I decide on my niche. A friend said it was too vague, although “a ton” makes sense to me.

Does the niche wording always have to come from my target audience to be compelling?
