When I first started doing the insane title I had read many guides (most of them well written) that had tips on how to raise reputation with each faction. The only one that I believed it was poor covered was the Darkmoon faire and that because there are many aspects someone should be aware in order not to spend way too much gold for it.
If you do have about 100k ++ gold and you don't care spending it then this guide is not good for you. If you don't then this a spreadsheet that might get very handy.
When I stared raising Darkmoon rep I had no idea how much gold should I spend in order to raise reputation cheap and no idea which cards to get.
Should I get the epic ones or the green? or the blue?
Which epic ones should go for? 60, 70 or 80?
How much money should I spend for each card?
How much money should I spend for herbs?
How much money should I spend for inks and pigments?
After buying things and spending a lot of time on my server's economy I realized that the optimal price (and feasible) for me is 0.5 Gold Per Reputation (GPR). In other words for 37000 reputation total needed to get from 2000/6000 friendly to Exalted you will need 18500 gold.
The following spreadsheet is the one I made by myself and I am currently using it for my rep grind. You will notice that I do not include prices for crafted 70 lvl and 80 lvl cards since the material prices on my server are way too costly to support it.
