Lol, your an optimist... I was actually meaning that the experts that do that, probably have tons of time and experience, trial and error into it. If you don't have disposable money to learn on, I would just buy one. If money isn't an object, then by all means, give it a go. I'm sure there are tricks and such that only experience will teach you. Kind of like with cooking. Where once you have a good feel for, and acquaintance with cooking, you can cook foods, or recipes with out measuring, because "you just know" how much or what you need. But, if you really want to try, don't listen to us, lol.
