English accountant needed

Good morning.

I am a sole trader in Poland - Warsaw.
About 50% of my business is online sell - (Amazon and eBay).

I need an accountant for book keeping and to calculate the VAT and income tax payment.
Can anyone recommend any?
I called more then 10+ but so far no one have any experience or knowledge on how can I make the declaration.

Why do you need to declare your income to HMRC if you are selling and receiving all your income to your Polish bank account?

Hello,

Because my products are stored in U.K, so I have to be VAT registered in the U.K.
