What is the make of the car? . It's not a major job on most cars. If you or a friend, know a young machanic - he would do it for a nominal fee (outside working hours)
This should not be too difficult of a job on a Ford Focus. (Fords are D.I.Y Friendly) Get a Haynes Manual (under €20-00) & a set of wrenches & you will be surprised how easy it is.
