Question about installing new gauge panel. Help

[spidermn]

I am starting to re due the interior of my truck and i am looking at changing my old bezel and gauges for a updated version with AutoMeter gauges in it. Well i have seen a few post on this but i am not too comfortable doing all the work by myself. My question is how hard will it be to do this myself or would it be better to just pay someone to do it for me? I will be keeping the Speedometer mechanical so i won't have to do any other electrical. Can anyone help me out with this one. Maybe even some tricks and knowledge on what and how to do it. Thanks
