Neeeed Runecrafting Help

[rsvlogster]

My Runecrafting is level 60. (275,190 exp)
I need level 70 to have all my levels 70+
I need some advice and some calculations done for me as I am horrible when it comes to knowledge about runecrafting.
I need to know:
-The best method in regards to cost and exp (Just what it is, I can probably find a guide).
-How many pure essence I will need.
-How much starting cash.
-How much I will make/lose
-How long it will take me
Thanks, sorry, I know it's a lot but I am curious

What hermes said, but I'd have to say the Abyss since you're doing it legit.
