Tips on how to reach 100

I currently hold a neohome/ neogarden shop and I'm size 33. I belong to a pretty well organized mall and I sell my prices in the wiz league. Does anyone have tips on how to reach the size 100 quickly? Should I rely on sales only? I have 60k right now

Sorry for the double -post. But my Neopets username is centermiddle. I'm also looking for someone to make me a nice neohome shop banner. http://www.neopets.com/browseshop.phtml?owner=centermiddle Furniture at wiz-prices!
