Qtek.nl has taken devices (from their dutch customers) and gotten them repairs. I don't know of any webshop that offers them directly, though. Stylus - yes.. the rest - no.
That said, you could persuade your device's retailer to order the parts. You (and they) can find the part numbers in the HTC Wizard service manual - which conveniently got uploaded here a day back;
