paying 1 DB per 8 EM Blocks

I am appalled at the state of this server. books are overpriced and no one is supply building blocks on bulk for reasonable prices.
you have 30 days to get it together. I estimate that's how long it will take me to setup my shop, restock and reacquire dedicated suppliers and work force. So if you don't want a price war from Humfry's House of Color 4.0 get it together.
As for my lower customer and suppler base message privately I may be restarting.

diamond to emerald 1 to 8
iron to diamond 32 to 1
gold to diamond 48 to 1
Would you say this is closer?

Ok I know this has been discussed before and people will say whatever you can get someone to pay is the amount.

But i would like to have a serious discussion of what is considered a fair exchange rate among most regular players.

so what i want to do is make a short list of basic exchange for reference:

Diamonds to emeralds? rate: my opinion is 8 emeralds per 1 diamond or 1 emerald block to 1 diamond block is fair both ways.
diamonds to iron? rate: my opinion iron might be 18 to 27 to 1 diamond
diamonds to gold? rate: my opinion gold might be 27 to 1 diamond

All other items i consider supply and demand.
I just want feedback on diamonds, iron , emerald and gold exchange.
please give constructive criticism and what you personally think is fair to both sides of the trade.

@FieryPhoenix64 What do you mean? Me buying my stock off your shop?

Actually I currently dont have a shop. I am considering restarting a shop. but I do have a lot of stuff I woudnt mind selling in bulk to you at 1/2 your price so you could stock up and still make a profit.
such as blaze rods and magma cream, that way i dont under cut your shop by selling cheaper directly. I dont want to kill the economy.

3.0 coming to a server near you..................

Will you buy conduits for 1/2 price?

what I am asking is dropped head names . I used an alt and we head farmed the name. if i change player account name from fred to george, will the dropped heads name change also? if yes then i wont change the name its a special head name.
