If they're on a budget and the job is straightforward then consider having one of the folks on FB do it - the hobbyists/side hustle folks.
A wee bit up the scale is Fraser Car Wash around Fraser/45th:

A little further up the scale is something like Burnaby Auto Spa (
https://burnabyautospa.com) - I used them for an interior detail a while back on my Mazda 3 and it was good solid work. They crank through their cars - lots and lots of volume.
Tiago's Autospa near Science World is a fairly fancy but I've heard only good things about them. I use RDI detailing in Richmond for my ceramic coating and they do regular detailing as well - pricey and a bit out of the way though but top notch work.
