Need greenhouse help, please

[JTPT]

Hello, my husband and I are getting ready to move from Miami, Fl. to Colorado. We will be bringing our children -about 450+ orchids and our dog - with us. :-) Most of our orchids are hanging under a pergola outside (approx. 500 sq ft) that wraps the side and back area of our home. The pergola is long and narrow.

My husband is convinced he needs a 14 ft x 30 ft greenhouse, but I think that's a lot more than we need! We've spoken with a couple of greenhouse companies already, BUT I'M HOPING SOMEONE CAN HELP US DETERMINE WHAT SIZE WE NEED. Also, any greenhouse company recommendations is VERY APPRECIATED, along with suggestions on greenhouse necessities and amenities.

THANK YOU IN ADVANCE! Wishing all a peaceful holiday season!
