You could probably get that lot done for a grand.
Easily, the only potentially expensive bit there is are the drive shafts.
Break service - £300ish
CV gator - £30
Replacing suspension arms - £200
The places where you'll save the money
door handle/carrier - bit of a fiddly job but probably 1-2 hrs to sort plus the part so lets guess at £75
Drive Shafts - these are likely to be a few hundred each plus a time consuming job to fit. You could use second hand parts and get a quote from some one, i would have thought this job isn't urgent.
Parking Sensors - I would get the fault diagnosed and a quote, but again i don't see this as a priority.
