Financial services company that handles everything for me (in the UK)

I'm looking for a trustworthy financial services company that takes care of everything and lets me focus on my business. It should cover incorporation, accounting, tax filing, local address, nominee services (optional), bank warm intro (optional).

Some services advertise helping you to open a business bank account but many people are saying that it's impossible to do it if you're not a UK resident.

I'm looking for something like Estonia's leapin.eu but for the UK. I'm not a UK resident (but I'm in the EU).

There are a lot of websites out there advertising those services but I'd prefer a direct recommendation from someone that has personal experience with such a company.

Also, what would be the cost look like for everything for the first year? For Estonia I know it's LeapIN fees + e-resident card fees + incorporation fees. For the UK case, it's not clear.
