Nomad's Requiem (Whole Thing)

I'd like someone to do the whole Nomad's Requiem quest for me.

Tell me how much it'll cost please, and how long it will take.

I'll only take someone trusted. Preferably 20+ vouches.

My skills are:

Attack: 95
Strength: 78
Defence: 71
Ranged: 75
Magic: 77
Prayer: 71

EDIT: I got up to the Avatar. Anyone wanna kill him for me? Add me on MSN!
