Domain / URL wildcard or Alias

Hi, I have a wordpress site, where my client wants to add city names in the url for example. The regular working url is:

http://www.website.com/services

They want to be able to do something like this:

http://www.website.com/miami/services

OR

http://www.website.com/services/miami

Keep in mind, we are not looking to create a category, the “miami” in the url is a dynamic variable that can be ANYTHING.

Overall, they all go to the same content page but have the ability to prepend or append the URL with a dynamic variable such as a city name.

Is this possible with a plugin, or do I have to modify the .htaccess file somehow?

Any help or guidance would be super appreciated 🙂

Thanks
