2.

Choose between two places to mine.

1. Transport by the wizard in the basement of the Wizard's Tower, and then walk to Draynor Bank to deposit the essences.
2. Transport by Aubury in the Varrock Rune Shop, and then walk to the East Varrock Bank. This is highly recommended, as the distance between the mine and bank is closer, and you don't need to worry about the jail-guards attacking you; so you can get mine more in a shorter time. Spend an hour on this and you'll soon get 1000 essences.

3.

Each essence goes for 75gp each, so make sure you get a handful to trade.
They are usually sold in the thousands. Before trading in the Grand Exchange,
North-West of Varrock, make sure that the essences are in notes.

1000 Rune Essence sells for 75k.
75k an hour at level 3 ain't bad. :P
