Inquiry to clean up my computer and optimize performance

I'm looking for someone to clean up my computer and improve its performance. I use a Windows PC with 8 years of files and several programs open all the time. Tasks include removing temporary files, organizing downloads, uninstalling unused apps, cleaning up startup programs, updating drivers, and running a basic malware/virus scan. I would also like recommendations on storage cleanup and a brief tune-up to speed things up. Ideally, you can explain steps clearly and perform any straightforward fixes remotely or on-site if needed. I value careful data handling and a quick turnaround.
