Welcome!!!
If you're handy and the rack doesn't have internal corrosion you can do it yourself -
www.rennbay.com has rebuild kits for the rack as well as the pump, and do yourself a favor and replace the reservoir as they are cheap and contain the internal filter for the system.
Please add the details of your car to your signature in the User CP tab and you can avoid the repetition of listing your car in the future.
I think you'll find the folks on here very helpful and unlike other P-car forums friendly and non-judgy.
