Hi Kyle. Thanks for your interest in our calendar plugin and its add-ons.
First thing to do is install our free “core” plugin from https://wordpress.org/plugins/the-events-calendar/
It’s required for all the add-ons to work. It also has a great display option to output “all”, “some”, or “hardly-any” of the plugin’s CSS — so you can definitely use your own.
The main add-on you’re likely interested in is PRO. PRO makes it easy to add additional custom field data to events and adds search functionality. You can see our demo site for an example.
You may also like the features found in Filter Bar. According to our feature voting system, searching by custom field data is a planned enhancement — so stay tuned for that functionality.
And since you mentioned “price”, we have Tickets integrations with several popular WordPress e-commerce plugins. And, yes, users can also search by price via Filter Bar (watch the video on the Filter Bar page, linked in the previous paragraph).
Last but not least, we have a pretty great Refund Policy so you can buy one or many of our add-ons and thoroughly test them.
Let me know if you have any follow-up questions.
