The coal exchange center.

OK, so many of you have heard that I got 60 mining earlier today (18th Jan 2014) So, I'd like to start a service that sells you coal for things (like seriously did that make sense?).

So, my current mining level is 60, I'm aiming for 85 (at least)

Anyway, so here are somethings that I'd like to have, exchanged for coal of course:

Amount of Coal I can give you ---> Item
1 coal --------------------------> 200-250gp
1 coal --------------------------> 1 iron ore/bar
1 coal --------------------------> 1 rune/pure ess
1 coal --------------------------> 1 of any uncut up to sapphire
2 coal --------------------------> Steel Bar
2 coal --------------------------> 1 uncut emerald
2 coal --------------------------> 1 maple log
3 coal --------------------------> 1 Law/Nature rune
