Installing own lift kit or getting someone else to do it?

[buckmontana]

Hi,

I've got a 2003 1500 Suburban 4WD and I'd like to put a 6 or 7.5" lift kit on it. I'm pretty handy with motors, but I've only got a standard home garage and basic tools. Could I realistically install a lift kit myself, or is it better (and almost as economical) to get it done at a shop?

Thanks in advance, Buck
