What software do you use to collaborate on small one-shot projects with freelancers?

I have used many tools during my professional work as a software dev, and now I’m collaborating with copywriters and designers for my own small projects. I feel like most of the tools are not really good for that. They are huge and focus on long term projects. What I want is simply a place to have some short lived gigs – prepare a design for a web page, poster, presentation, etc. My use case is just 3 people from my company collaborating with 1–2 freelancers per project.

What I need is something like a wiki page (markdown) + chat board + files (versioned + comments) + todo list with reminders. I would create a new page for each gig. It should just be easy to archive and search through them. No need to track time, kanban board or anything like that. Just a single place of truth about work we've ordered, communication history and all deliverables.

Also pricing model for most of the tools i have used is not really good for this way of working. My projects are very short (1–2 weeks) and freelancers change. Don’t want to have to pay for 10 accounts for whole year so I can work with 7 freelancers for 10 days each.

Do you have any advice on that? I feel like most of project management tools are made for big teams or for agencies. But I want work for me to be kept in my system.
