Does anybody need to turn their SaaS product into a mobile app?

I’m considering starting a side hustle that is an app studio focused on creating cross-platform mobile apps for existing SaaS / micro-SaaS products.

Would anyone here be interested in that service? Would anyone have an immediate need for something like that?For the right partners I’d be willing to work at cost to build out a portfolio. How
much would you pay for such a service?

Thanks,
