Remodeling home...consult architect or interior designer first?

I am planning on remodeling our very tiny galley kitchen and adjoining family room by expanding out about 8 feet. The problem is, neither one of us has an eye for what goes together. We both know what we like/don't like when we see it, but just aren't creative enough to coordinate things on our own. So, are we better off getting an interior designer's perspective first, or hiring an architect? Are architects trained in any way to help people decide on things like what countertop color looks...
