Do you have any overarching theme for the shop? Or are you simply looking for a name?

Are you looking to have a custom plugin built?

Depending on most plugins present in your plugin shop you can name it accordingly. For example, if your shop is dominated by e-commerce plugins you name it accordingly. The great news about these WordPress ecommerce plugins is that they provide the same features and benefits as SaaS products, and you receive excellent support resources, thriving development communities, and an integration with the easiest content management system in the world.
