Accounts, Cooperation TAX, Dividends payment

I have a small Architectural company where I am the sole director / employee. Kinsonov ltd set up in November 2019. The turnover is around 20K and that is literally from 3 projects (4 invoices or so).

I'm looking to organize my accounts and salary (I was told this is better done through dividends rather tan PAYE); File personal self assessment as well as cooperation tax and company accounts.

Please let me know if this is something you are able to help me with.

Kind Regards,
Sergey
