Right now I can't commit to having anything ready by a particular time since I am still doing research. Yes, all of the rock would be cured. It will be made out of "aragocrete" as seen on GARF website (portland cement, sand, gravel, water, possibly plastic shavings). As I said, I will have to perfect the making of it first. I am not sure what to charge yet. I will have to calculate what the materials and time will run me first.
