I've been working for various companies around the city of Omaha for almost two years now, doing monthly chalkboards for them. I love the millions of different lettering combinations there are out there and incorporate them with more traditional art to create an all-around image.
I do chalk walls in companies or simple boards for cafes and coffee houses.
The costs are typically per square foot if you want a chalkboard make-over. After that, it depends upon what needs to be changed. Phrases, lists, and etcetera come in block prices.
I love working with various ministries, so please let me know if you are non-profit or part of a worthy ministry. I can work on pricing or even a barter-system.
I'm still developing, so I'd love to experiment with you!
