Sysops Freelancer to complement Laravel Developer

I'm a really good PHP developer who's ended up running a server because one of my projects has outgrown the semi-managed hosting I usually use (from CloudWays.com).

I'm looking for a sysops/sysdmin to help manage my production server, and advise on adding a staging environment to it (without having to duplicate all the services). I'd like you to take responsibility for making sure it's fit for purpose and maintaining it's uptime - including being on call should it go down.

The server is managed via Ploi.io (but I'm open to that changing):
NGINX/MariaDB
Laravel including large numbers of Jobs in the queue
Redis
Docker running OSRM, OverPass and Postcodes.io containers
A Web-Sockets server

I'd also like to be able to call on you for "tech-support" for my development machine, which is a LAMP stack running in Docker containers - but I'd like to migrate it to WSL.

If you think you're the right kind of sysops for me, please get in touch to let me know why :)
