Need advice on financial requirements, which of my assets should I use?

Hi, I was wondering if you could advise me regarding the financial requirements for the spouse visa. I was reading the financial requirements document, but I have a hard time understanding it because there is so much content. I’m hesitant to pay for a lawyer as I only know of ones that charge a full application fee, which I’ve had no problem with, it’s just this section, and I don’t know if anyone would fill in the section for me or help with payment only for this section.

This is my current situation below and I would appreciate any guidance on financial need to use;

I am the sole director/employee of a limited liability company – to which I provide locum healthcare services. I took dividends of £15.6k 4 months ago. I pay myself £760 a month from my company. My cash savings are currently £42,000, but it’s only been 4 months, where I’ve transferred a lot of my dividends and expenses. Prior to this, my cash savings were £9,000.

I have also received over £8000 in support to buy ISA over the last year. I do not have audited/unaudited accounts for my company, I have just filed my usual accounts myself at the end of the financial years. What would be the easiest way to show my financial needs?
