congratulations on your upcoming wedding?
If this is a one off event, a temporary marquee and structure will be built and taken down after the event to fit your exact specifications

If you are looking to build a permanent structure then you should hire a local architect and discuss your ideas with them.

hi there, thank you for the congratulations but i am not getting married : ) i am actually a wedding planner. I am working with a couple who just bought a property and are making it into a wedding venue. They're currently building a pond but that's about it. I'm looking for someone to help design some curb appeal, but in some pretty stone work, etc. I wasn't sure if I should be looking for an architect or landscape designer?

Sorry Abby (hence the ? (!) - It sounds like you need a landscape architect
All the best

You may want to look into a designer who specializes in commercial properties.
