Online car radio codes

Grumpysally

I've recently had work done on my car. The battery must have been disconnected as the radio is now not working. I don't have the code. 
I've done an online search and found out how to find the information I need to get the code. I don't have time to take it in to a dealership. Can anyone recommend an online code seller. I've looked at several and the price varies greatly. I want to avoid getting ripped off.
Thank you

Make, model and serial number of radio.

Quote ALL information on labels case etc.

We can then find the code if it is possible or advise if main dealer or radio specialist is required.
