Sharing projects and tools with team

So I have a small team of 3 including myself that have been working on building a world for a future game of ours. So my question is we’ve been working on just one computer (my computer) because I had bought content and tools for the project. We are trying to figure out how to be able to spread out the work load but it would be way out of budget to have the rest of the team buy the same assets and tools. Is there a way to share the project with the assets and tools? (The main tools are several of the brushify tools and a few assets)
