DOOF...
I also agree you should do it yourself. You will feel good that you modded your car yourself. I have always done all my mods and work myself on all my cars since i have gained the knowledge. The stuff you are planning to do is fairly easy.
As for the poncams and timing light...If your motor is already timed correctly prior to installation, you can just set the motor on tdc and mark the cas's location. Put everything back exactly how it was after install and away you go...timing will be the same.
If you need any help/advice with it, feel free to ask. Ive done all these mods before.
PS. Boobies ftw!!
