Networking and Virtualization for existing servers

I am looking for an experienced freelancer to help me with my network and virtualization project. I have an existing server setup and I am looking for someone to design and maintain the network. I am not sure if I need to migrate the existing servers, so I am looking for someone to advise me on the best way forward. It may also be necessary to invest in additional hardware for the project, so I am open to suggestions and recommendations. The ideal freelancer for this project should have a proven track record in designing and maintaining networks, helping with a server migration, and selection of additional hardware, if needed. Currently, we are having issues with the speed of the remote desktop speed, and looking for suggestions for the best software to set up or develop a new solution to use through a web browser.
