Hey @Michael,
Thanks for reaching out! While we cannot help with customizations and modifications, and adding things like costs, venues, etc. is a complicated customization to make, I would be happy to take a look at your site firsthand and recommend some CSS that might help.
To that end, can you share a link to your site where the widget in your screenshot is visible?
I will take a look.
For those other customizations, these would unfortunately require many code customizations to implement. 🙁
So to implement those features you describe, you would have to write that custom code or hire a professional developer to do it for you. We have a list of great developers here → http://m.tri.be/18k1 (and have no affiliation with any of these folks—they’re simply some well-respected names in the community that we’ve compiled to share in situations like this one).
Cheers!
George
