On Minecraft I do lots of building (not redstone building unless it's simple redstone building). I will give up some of my time so I can build something for you for the fee of 1-7 grass (depending on size) and 1 iron ingot per build.

I can supply cobblestone (and acacia planks for an extra charge of 1 iron ingot but only 32), however, you need to supply anything else. If you want stone materials, e.g. Stone bricks, you need to supply coal or charcoal and I can do the crafting and smelting.

You will need to be a donor otherwise you can't teleport me to your island. We will also need to agree on a time and day.

The kind of things I could build would be animal pens, dog and/or cat houses, enchanting and brewing rooms, farms (I can provide a hoe for free) etc.

Please comment if you would like this.
