I have an idea!!!
Buy one from TC and then send it to Puppy Wraps!!! Have her INSTALL a door!! Like in a tent! it'll just be a long zipper that goes all the way around and it can have strong mesh as the door... if you hit the fabric store and find some or she probably can grab some on one of her trips to the fabric store! She does TOP NOTCH work!! And it would be a really nice looking finished product!! Like you bought it that way!!!
Check it out!!! PM her!!
