Ok...from a shop owner.....(I have a shop that is going into year #3 of business)....
Do you know how to do alarms? Remote Starts? A basic keyless entry? How about adding doorlock actuators? What if the door locks are cable driven? Do you know how to do release solenoids? Do you know how to trouble shoot? Do you know how to properly look for the best spot to run a power wire? How about properly grounding an amplifier/headunit/alarm or anything? Do you know how to take apart a vehicle WITHOUT instructions telling you how to do so? Do you know how to acutally solder? How about installing monitors in new locations (headrest, drop downs, custom fabrication)?
If you can't get a LOC in a BMW to work right....you shouldn't even consider opening a shop...I'm not trying to be a jerk...but you don't have the necessary abilities to do so.
As for "hiring" someone to work for you and do installs....ok...lets look at this....he/she is going to want to be paid...every week... now you might be ok here if you pay based on the amount of output...but just starting out he is going to starve..and basically unless you have about $50K so will you....
As for the recession comments...the economy isn't in the $hitter everywhere...in fact I had a stronger March 09 then I did December 08.....and I had a good holiday rush //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif If you dont have any experience...EXPERIENCE EXPERIENCE EXPERIENCE.........dont open a shop... go to work for a shop and cut your teeth, then when you feel comfortable handling anything that comes in door, then if you have the money situtation right, and only then...pursue it... not until then...
