Have used Pharos for a lot of questing, skilling and other services in the past. Very nice staff, good workers and priced fairly. Never had any issues with them.
Huge vouch for @Pharos service. Trusted the man and his brothers with over a 8.5B bank on my main. He finished Zuk helm for me in about 42 days. This included several hundred raids. Can't vouch for someone more, he's just a great guy.
