2002 lincoln lse r/s suggestions, guidance

I have a customer who would like to me to install a remote start into his 2002 Lincoln LSE, I don't know much about the car except that it does have the factory alarm system installed.  He works across the street, so anything I need to find out about is easily done.

Ok, the problem is this.  I have never installed a remote start before, and only a few alarms, but this is something that I am trying to learn so that I can offer this service out of my  car audio shop.  Should I undertake this job, he knows that I have never installed one of these and he doesn't care about being my guinea pig.  The fact that this is a Lincoln kind of has me scared.  Should I go ahead and do this?  If I do, does anyone have any suggestions as to some of the more reputable brands of alarm/RS systems that I should look into. Any pointers into which direction to head into first would be very helpful.

Thanks in advance for your help.

Thanks for your reply, it must be an LS, I thought it said LSE on the trunk lid.  I appreciate your info, thanks again
