Learn to do the basics yourself.
An emergency kit, etc. triggers much advice and many suggestions. I'm more of a minimalist and carry 2 tire levers, spare tube, tube patch kit, 2 CO2 cartridges and the head for them, a small allen wrench kit and 3 one dollar bills in a small under seat bag. Other than flat repair I've seldom used any of them but nice to know they are there.

Some bike shops offer basic bike repair classes during their slow/winter seasons. We always do and they are generally filled. We teach how to deal with a loose/broken spoke, change a tube/repair a tube, minor derailleur adjustments, cleaning and lube tips, tricks and methods we prefer. We have had a lot of positive feedback on how it helped either them or another during a ride, etc.
There are also some very good videos on You Tube.
