As an extra perk to your premium membership you can ask me for a code review of your WordPress plugin. I will review your code free of charge and offer my critiques and suggestions.
This is a great way for you, especially if you are still learning your way around WordPress, to help ensure your plugin is up to par and is not going to cause problems. I will never confess to or claim to be a perfect plugin developer, but I do know that an extra set of eyes always helps, and I have written quite a few WordPress plugins.
Note, theme reviews will also be accepted.
