When designing a custom deck, make one using a design that you like, using stock and finish that you like. Don't do it for others. Do it for yourself. If you really dedicate yourself and take the time to do a deck that you love, some will like it, some won't, but you will have the feeling deep down that you built something truly unique. If you do it for others to like, and they don't, you'll get no gratification out of it.
In order to know exactly which stock and finish you want, there is nothing like handling them yourself, reading about it only gives you information, not feel. I would advise you use your money to buy already printed custom cards of various stock, finish, and printer. Don't take others word on it. Find what you like.
The same can be said about the card design: back, pips, and courts. Buy cards of various design, and see what you like. Designs might look nice in pictures, but when handling and playing them, you come to see them differently. Again personal taste comes into play. Find what you like.

Jim Morrison said,
"If you book them, they will come."
...
Wayne - None of the bands have shown up.
Jim - I know, and they're not gonna show up.
Wayne - Then why were we supposed to put on a concert?
Jim - Because you had to try and do something with your life.
Wayne - But it was a failure.
Jim - Whether you won or lost, what's important is that you gave it your best shot.
...
Jim - You'll think of something. It's your movie.
