I know how you want them done as you explained earlier, but if you check out the site above, it will give you an idea of whats available.
If you take it to an auto electrician, all you will need to supply are the lights. He will have all the other stuff, such as wiring and connectors ect.
If you are doing it yourself, you will need......
Wire strippers.
Side cutters.
Crimping tool.
Selection of crimp connectors/terminals.
Soldering iron.
Cable ties.
Electrical tape.
Screw drivers.
A ton of wire. (Don't use all the same colour as it will be a nightmare if trying to diagnose a fault).
A length of coat hanger wire for a pull through (Optional).
Multi meter and/or test light.
Car manual or knowledge of wiring circuit.
Plenty of patience.
Flexible joints so as you can get under the dash and seats.
A few hours.
And anything else I've forgotten.
