I believe you.
You see Charlie, we get about one thread like this every six months...they always start off bad when a guy says "money no object" because it strikes some the wrong way - not me...you asked a question, and I gave you an intelligent answer, as did lots of others.
I have a friend in Minneapolis that used to run THE high end audio shop, so he would get all the young punks with the multi-million dollar contracts rolling in asking for this and that...money is no object, etc. Timberwolves, Vikings, North Stars back in the day and now The Wild players, etc...it's cool to have money and success, but how you carry yourself separates the guys who are successful that everyone likes from the arrogant pricks. You are young, so you have time to choose your path before you make the big-time, and I hope you do. If you are smart it can be a life changing experience. If you are not, you will be 40 and broke with injuries. I have two cousins that played NFL so I've seen how it can go.
We have a lot of fun on this forum, so taking a little crap is par for the course. Welcome aboard. Stick around, and you'll learn some stuff.
Now, back to this Mustang building. First off, excellent choice in car.
There are guys on here running every kind of mod you can imagine..from pure race cars with parachutes and roll cages to daily driver cars with over 600 RWHP.
I still personally think that your best bet is to decide what you will primarily use the car for, and then find a good speed shop to build it for you. You will likely be too busy to be wrenching on it yourself with your schedule. I know guys in ATL that can do it from the ground up...and places like JDM can do that as well.
