Financial services is a sector where you need connections just as much as capital.
Unlike building for example a SaaS business around a good product idea, in financial services, it's not only a matter of finding developers, marketing, customer support, and sales. You also need connections within the financial services sector to have a chance at being taken seriously (and not get ripped off) when speaking with banks, VASPs, PSPs, and so on. If your business plan includes getting a license, you need even more money — both for regulatory obligations but also to hire a whole legal/compliance team. If you handle card payments, you need to consider PCI-DSS compliance.
Good connections are hard to make. Practically every successful founder in this industry first spent a few years in the industry. Those who didn't hired people from the industry: by poaching good people from competing business and/or hiring freelancing consultants.
I appreciate the consideration but I'm not the right person for this at this point unfortunately.
I could be wrong but I get the feeling you're interested in starting a business without really knowing what or what for. It sounds like you have the right ambition and drive, and combined with the ability to raise capital and tech resources — all you're missing is an idea that you're passionate about. Go find that idea (on your own or with cofounders), and then start your journey.
