Hi! I actually worked on that exact feature. I definitely know what you mean about lack of refinement options on that page, though you can refine (roughly) by price. Also, email's in my profile, so hit me up if you wanna swing by the office.
Just a heads up. Your email is not visible in your profile. The "email" field isn't visible to other people. If you want us to be able to see you email, you need to add it to the "about" section.
