Start at :
then click on: find an architect
when left side of page comes up click on : Find an architect
then click your state:
quite a few for ND come up but none specific for musuems - there is an 800 number (some where in this site)
What type of budget do you have? Musuems are a "speciality", and if there is not a firm that specializes, you should look outside your state.
Good luck
