Sounds like a fun little project, I wouldn't go crazy spending tons of money on decorations, I know when I walk into a garage I am not worried about how fancy the waiting room and owners office is, but I like to see a nice clean work space and pictures of cars they built on the walls, with letters from happy customers, that would make me feel a lot better than an old gas pump and some fancy tractor seats to sit on (I am referring to a local resto shop that I will not do the service of mentioning their name, if you been there you will know, lol)...
Anyway, I do something similar, I am self employed and help out local guys, I let a few guys use my lift and my tools when they are in a jam or have something to do. When I was with the chevelle crowd I swapped 4 (I can think of off the top of my head) motors for guys, bring a few 6 packs over on a saturday and your work clothes, she'll be running by sunday night, no matter what...
NOW,, to make a profit doing brake jobs is tough, I am going to go out on a limb here and say its much tougher doing JUST vintage vehicles, since there are many less and they dont drive them as much to need brakes constantly.
To do a shop right you need to make the connections and establish relationships with the outside businesses...
LIKE- get an awesome tranny shop on board to do your rebuilds for short money and do a good job, SO when you stumble upon a turbo 350, turbo 400, power glide, 700r4, 200r4, 727, 904, 833, m22, etc etc etc you can have them rebuild them and put them on the shelf, BELIEVE me when a car comes in with a blown out 727 and the guy wants it back on the road, that rebuilt tranny is worth a lot of money, considering you can have him on the road in 4 hours!!!! Then take his core and have it rebuilt.. I know a shop that has about 15 trannies on the shelf, and he charges a bit for them, BUT who else gets you going that day?!?!?!?!
A good chrome shop, nice to just send something out and make 10% when it comes back all shiny..
Next would be a good body shop, its nice to make 5% on a paint job and just deliver the car, its simple, you find a shop that will work with you, you bring the work in, they give you 5% commission and save your customer a few percent at the same time....
I always thought there was a lot of money left ton the table in parts restoration, its a simple premise, you make a recipe book,
-Rebuild manual pedal set $125 (glass bead, coat, and reassemble with new bushings and bearings).
-Rebuild steering column $400
-rebuild console -$350
Offering these services will keep your employees busy and turn a little profit...
I think it can work, there is a lot of money in resto work and maintenance. I think in FL you would be smart to do corvettes also, it seems there are a ton of them down there...
Also get a tax id number so you can setup distributor accounts with year one, classic, etc etc etc so you can give us all parts at cost
