Fitting Reversing Camera, And New Audio System

[scotsmac]

Please, I live in SW London. I have a Transporter T28 Highline, that is transformed into Camper Van with pop up roof.
Now I would like put in reversing camera and new radio, thats compatible with the camera.
Also I have a Tow bar, Bike rack and Cargo box on rear, at times, and my Van has Barn Doors.
Can anyone recommend a good system, and more important a GOOD company to instal it for me, in SW London ? Or any call out companies to fit this for me.
I would need this installed and run it comparable with speakers already fitted.
