Can I pay someone to setup a Digital Ocean droplet for me?
Using Jamroom
Have you looked at the guide for doing this?

It really is pretty straightforward if you follow this to the letter.
The DO servers are 'self maintained' so even if someone sets it up for you, you would still need to maintain/upgrade etc. on a regular basis so its worthwhile doing things yourself and getting the hang of things there.
