One option you might want to consider is a two stage pearl...where the pearl is in the base coat rather than being applied in an "inter coat" or middle stage between the base and clear. Obviously you will never quite achieve three stage results with a two stage paint...but the challenges are also much less frightening.
You can see a bunch of pictures of my two stage pearl
here. This was not only my first experience with a pearl, it was my first time shooting BC/CC. So I needed to keep things as simple as possible, yet try to get some pearl effect.
This will give you an idea of the final effect. (First two shots taken before cutting and buffing. Last shot after buffing.)
Which ever way you choose to go, there are some great painters on this site with tons of experience to share. They were a great help to me all along the way.
