Wouldn't be too complicated to do, but probably a bitch if the CVs dont go back on properly. And the CV nuts will probably be incredibly tight

2 hours would be a bit over the top for 2 CV boots I reckon, probably take one and a bit just to allow for everything. Some garages will have a tool for stretching the CV boot over the CV so you dont need to take it off which saves a fair bit of time.
If you want to do it yourself (explaining one side here) then you need to take the CV nut off (the one that you can see through the middle of your wheel, probably a 30mm or so), remove wheel, disconnect ball joint or bottom arm (whatever is easier), pull CV out of hub, pull hub out of the way, get the CV off (probably do it with a hammer, otherwise take the half shaft out and get the CV off with a hammer in the vice), put the new boot on, bash the CV back on and do the clips up on the CV boot, put everything back together.
