If you're playing Black version, you can rebattle the people in Black City daily. Not only is this good for experience, but the mayor gives you 10,000 Pokedollars for 10 people beat (the number rolls over from day to day). Although the number of people in the city (as well as the size of the city itself) changes depending onhow many days of playing the game ti took you to reach it. There can be a max 21 trainers, but like my game only has 9. But you can increase this number by having friends come into your game via Entralink. The trainers pokemon are anywhere between 30 and 67.
