Want to add dashes to cell text...

Hello everyone,

I have a column of city names, some are one word and others are two or more. I am trying to take the city name and add it to another word, add dashes in between them and make everything lower case.

For example:
Column 1, Cell 1 is: San Diego

I'd like it to look like: books-san-diego (books being the keyword I'd like to insert before the city.)

Thanks for the help!
