The only requirement is that you must have Schematica. What you will do is take a mall design that I have already made on singleplayer and build it on my res. I'll give you the world download file and you just need to copy it over. Also, I will supply all blocks necessary for the build. When you take the world download, tell me the number of blocks needed too. Since all you need to do is transfer a design over, I will pay for your services, but not as much as if you were creating a design for me.
