I found the code of an old project - How do I monetize it effectively?

I recently found a piece of software I developed a while ago, I never actually used it, but it fits neatly into the "SAAS Tools for Entrepeneurs" category, and would certainly do well on platforms like AppSumo. (It's a design tool, which uses AI to generate social media ads)
Due to other project I'm currently really busy, so I want to monetize the software as a side project. My goal is to do this in a very time efficient manner, I intent to invest 5.000 Euros, to set the whole operation up.
Here is my current plan:

Pay someone on Fiverr to create a compelling brand identity and landing page
Setup Social Media accounts
Setup affiliate program, with a very generous compensation
Contact various blogs owners / "influencers" / people with a newsletter or platform in general, and offer them the ability to participate in the affiliate program (in the beginning I will offer a discount to the product, to get early sales)
Once I have some early traction, I will launch the product on PH and after that on AppSumo.
After the rush to the product has leveled off, I will set a reasonable price, and rely on the affiliate program or ads to get customers
Does this sound like a good plan to you? Which aspects of this process can I outsource? Or is there some way to just hire someone to take care of the whole marketing thing?

Looking forward to your suggestions.
