I'm looking for a word to describe someone who is not an expert in a field, but wisely lets experts do the work for them. An example would be someone who owns a cool old car but does not work on it at all themselves, instead paying a trusted mechanic do all the maintenance for them.
My issue is that words like "novice", "naif", "ignorant", "beginner", etc. all have a somewhat negative connotation. But in many cases, it's smart not to try to do things yourself, so that connotation is inappropriate.
I've searched around quite a bit on Google and on here and haven't found much, but would be happy to be pointed in the right direction if this question has been asked. I think the closest I've come is "dependent" or "reliant", but those also have a bit of a negative connotation.
