Taking an x5 to Meneike is an invitation for disaster. No matter what you decide, find an experienced mechanic and not one of those chain stores.

Plenty of YouTube videos on brake work and brake fluid changes for you to watch and judge for yourself.

Certainly nothing technically complicated compared to the work you listed but in the end, you have to assess your competence and comfort.
