Why u don't ask the shop to do it for u? Many many of them provide this service, and some of my friend also ask them to do everything, include tire glueing.
But those player know how to do and have skill on the track, its just they are affortable in term of $$ and no time on other thing except play.
End up don't ask the shop for the price breakdown per item and don't complain the shop over-charge u. This is the way of "some" adult, if u said other is 小朋友.
