Need my LS7 tuned because of the mods. Problem is who to take it to. Nobody in Las Vegas will do a start up tune and the one people reccomend is $900. I see better known names like Frost is only $550. What do the expert on this side of the country take their cars to?

Who did you contact here in town?
There are only a couple that I recommend
What pcm are you running? E38 ?
What mods?, I don't recall that you had anything very drastic, just a cam swap

Leading Edge Perfornance, I have the E67 ECM. I did a cam swap and had the heads CNC ported and upped the injector size to 65lbs. Other then that, long tube header, 3" exhaust, intake

Yeah, I wouldn't go to that shop at all
what size cam? 65# injectors may be overkill for it ( stock injectors are 42#)
All LS7 had the cnc ported heads
Stock intake/ (they perform well)
I can get you in contact with a couple good guys here in town
Does the E67 still have stock tune? or VATS removed , etc?

I ended up using the GM performance harness and ECM. It's already configured as a stand alone without VATs and emissions. It does have the stock LS7 tune on it. The heads were checked over by Texas Speed and they did the PRC 265 program to them. The cam is their Stage 2. They recommended the 65lb injectors since I needed new ones anyways.

I didn't even dare to try and start it knowing I modified the engine.....Could I?

Yes, you can start it

It isn't highly modifed, just a mild cam and larger injectors
You did measure both for correct pushrod length and PTV clearances, correct?
