I agree, those wire sections look like they have too big an opening. Since crickets will not be used I would not go for more than 1/2 inch openings on screen/wire/webbing.

Since you already have the screen and possibly wood, just make a frame, add a door and cover it with screen. (There is more to this than that but you know what I mean. After a while you will more than likely want to change the layout/structure anyway . . . It happens to all of us. Eventually you just might end up getting the cham cages anyway. I really like them and the are really easy to put together (take a part) and clean.

Not sure if we are on the same page with the heat bulb. As said in another post, you do not want to use a reptile "heat" bulb. They will get too hot! You just want the closest (branch) basking area to be in the high 80's - low 90's.

You would need to speak with the breeder on whether they are comfortable shipping to a specific location at a specific time of year (temp). The two that were mentioned above I have dealt with and have nothing but the best to say about them. If they say it is ok to ship then trust them.
