You really need to be doing this sort of stuff at home, unless as Jayton says, it's a very easy job (then why not do it yourself?)
These cars are uneconomical to keep going by paying for other people's labour!
Wheel bearings - knock them out and clean, regrease, replace using old bearing and or appropriate size socket to drift them in. Reassemble, use new split pins. Check play after a few days - tighten spangly nut if needed.
Drive shafts - wots wrong?
Power steering - there is an adjuster bolt to tension belt located on the bracket next to the pump pulley, don't forget to loosen the lock nut on the inside of the bracket beforehand.
Have fun
