For sure you don't want to spend that kind of money without customers/clients yet. The problem with a software-based startup is... software development is expensive. Not that contractors will rip you off charging too much for shoddy work -- although that happens, software is expensive even when it doesn't. If you are paying a consultancy for the software development, you should probably plan on spending six figures in consultancy invoices to even get an MVP -- if you mean an actually working app by "MVP". That's not a lot at all. So... up to you to figure out how to verify your business model before you do that (with an "MVP" that isn't actually a working app yet perhaps), or have a business plan that accommodates it.
