You will need to use a gel stain, as Maple is hard to stain to get an even finish.

General Finishes makes some dark finishes, like what you want.

I would advise getting a powdered analine dye that mixes with water, color could be cherry. Mix in warm water and strain through a paper paint strainer or a coffe filter into a jar. To apply use a old spray bottle like a Windex bottle wiping with a rag as you go. After it dries for about two days, and the color looks even, apply two or three coats of waterbased flat or semigloss. You could also rent or borrow a spray gun and spray it. Be sure to try the total process on a large scrap of maple first. You can order all this stuff on line. Hydracoat is a good clear finish.

There are a lot of companies out there that finish and refinish woodwork. Sherwin Williams, like a lot of other companies makes different kinds of stains. I believe the original poster wanted advice about the kind of stain to use like Amrad gave him because he wanted to do the work himself. The advertisement on the site you directed him to is misleading and false.
