Help for management of practial issues

Taxes - Hire an accountant

Insurance, Paying bills - Set up a standing order with your bank. (of have them paid by direct debit).

There is a service called Do It 4 Me. I expect when you see what they will charge you will do it for yourself

There are "off shore" personal assistant services (See 4H workweek). Most of these are for independent professionals, but you can easily find somebody on Upwork for example to make appointments for you etc.
