If you are worried about it becoming a money pit the track rod is a very easy job to tackle yourself and parts are cheap. You need a track rod, a RH end and a LH end (

link). I do not know you level of mecahincal skills but if it is zero this is about as simple as you can get to start learning. If you already know your way around the tool box you should be able to do it with your eyes closed.
To remove:
remove the bracket on the axle (13mm from memory)
Remove the split pin through the castellated nut
Loosen the nut (19mm from memory) but leave it on the end of the thread, do not remove it
Use ball joint splitter to split the joint
fully remove the nut
repeat for the other side
Carefully measure the length of the old track rod assembly and build up you new one to be the same length with an equal amount of adjustment at each end (do not screw on end in full and have the other one out to get the correct length)
In true Haynes fashion, refitting is the reverse of removal
The go to the garage to get the tracking done. Only allow them to adjust the rear track rod as that is all you have changed!
slightly different as it is refitting HD rods (I prefer standard as they are then the failure point) but give you an idea of the job:
