It depends on what you're looking for!

My chalk walls at the Stockroom start at $275 and increase depending on the level of detail. 

Seating charts start at $150. 

Most signage starts at $50 and increases depending on time and amount of work that goes into them. 

So... how does this work?

Usually my clients purchase mirrors or chalkboards themselves or rent their signs from other vendors. I get the signs from the clients around 2-3 weeks before the wedding and return them to the clients as quickly as they need them. Turn around time is around a week.
