03'stretched hummer H2

i got a guy with a streteched hummer h2 (limo) he wants an alarm system installed, with keyless entry, basic shock sensor, etc.. etc.. with one or two additional shock sensors mounted throught the vehicle, what would be a fair market price with parts and labor installed using either a dei or audiovox unit im thinking $250 for basic alarm with keyless installed and then about $85 for each additional sensor installed, so right around $400 installed, does that sound about right? just curious from some input from an experienced installer/retail shop owner thanks

That price sounds about right, providing you're taking the extra time to hide everything, install an extra siren or two, and so on. But I'd also advise that you try presenting him the whole system---tell him all the stuff you'll do, and how cool it's gonna be---all for $400 installed. He most likely won't ask what the exact breakdown is, as long as he thinks you'll do a good job. The last thing you need is to get to the point where he goes "Ah, well, then, I think I'll be okay with just one extra shock sensor," and you're stuck doing the job for $315. Also, unless you're installing a "keyless upgrade" alarm, you'll need a databus piece to control the doorlocks; be sure to add this to your $400, and explain why the extra part is needed. On the other hand, if you're already running wires to the rear of the car anyway...I hear you can get regular negative locks at the switch by the tailgate, and factory disarm in the driver's door.
