Is an MBA from Leeds School of Business, Boulder CO worth it?

I currently have an undergraduate degree in Architecture. Because of the job market is has been very difficult for me to find a stable a job. I have worked in many companies for 2 years as a drafter, architect intern, census taker, istant designer. Currently I am working part time in a construction company doing admin work and part time teaching Spanish to adults. I would like a career change, but don't know if the time and effort for an MBA will help or hinder me. I was thinking of getting an MBA focused in sustainability and real estate, and probably use my architecture background and work for a developer. Is this a smart move in this economy? Or should I just become a bilingual teacher in Denver? I am thinking of pursuing either an MBA or a Master's in Education. Please help! Thanks!
