I'm glad you're getting a new frog. But I'm also a little saddened about the sick one - my fingers are crossed for her but I'm not optimistic that the breeder would be able to do anything that your vet could not.

You should look into the basics of vivarium construction. Some good beginner advice here and here. There are also plenty of resources on this forum. A false bottom really isn't difficult to construct and it will make your life so much easier in the long run. What are the dimensions of your new tank?
