Diamond 1Pick where you are now and where you want to be, and the price is the rating between the two. Iron to Silver is cheap because those games are quick; Diamond to Ascendant is not, because they are not. Each band of the ladder has its own rate, which is why a long climb through the bottom costs less than the same distance at the top. Above Immortal you also state the rating inside your rank, because up there the rank is a band hundreds of points wide and the number is where you actually are.
A division is about a hundred rating, which is five wins, which is seven or eight games at the winrate a booster plays at. Call it two hours of play. The order page quotes a range in days for the exact climb you have configured before you pay. A booster can only play so many games a day without the account looking strange, so a long climb is spread across several days by design rather than rushed in one sitting.
By default the booster plays the account. Add duo queue and you keep playing your own account in the same party instead, which costs more because carrying a five stack with a fixed teammate is slower than playing alone, and which means your login never leaves your hands. Duo is also the only version of this that you learn anything from, since you are in the games.
