Youre asking a very vague question honestly - it all comes down to where you live, who you ask, where you go, etc...
You can go down the street to your garage mechanic and get the whole thing done for $400. You go to Toyota and that number could easily quadruple.
If you're limited on time but dont want to get raped, i'd just install those items slowly overtime. I mean HIDs take 30min to install but shops will probably charge you like $150-300?
The valences take 5minutes each....fog lights probably about an hour only because you'll spend most of your time taking off the bumper.
The lift isnt as bad as you think - the biggest pain is the rear springs - the shocks themselves are just a 1-1 swap.
