Just launched a successful SaaS product as an engineer, what can I do next?

Hello folks!

I'm an independent engineer and basically I finally managed to create a SaaS product completely by myself which is working.

Organically the product went from 0 to 10 K$ recurring monthly in less than a year, 10/20% growth each month, with 1 000 paid subscribers and almost 20K free accounts.

So I'm quite happy with that. But I have now big plans for this project and maybe looking to raise money to be able to create a small team around it and accelerate everything (do more marketing, development, etc.).

Unfortunately as a pure engineer I have 0 experience in writing business plans, create a pitch, etc, all the stuff that is required when you want to raise money.

My question is simple : is it possible to externalise this process, find someone or an agency who could help me in doing that? So that I could focus in continuing to develop this product instead of writing business plans/pitches, the stuff that I'm not good at.

Of course because the product is already making money each month, I could pay cash.

Thanks for your answers 👍🏻
