It does take a bit of time.

Running dailies with the team, should get you over 1k a day.
Which can be used to buy some BoE's, which will help out a lot.
You're better off with several iLV 200-213 pieces, then with a big 245-264 piece.

Also, if you can run several random heroics as only a tank.
Over the course of a weekend, you should have a lot of gear.
And the tank is the key position for most boxing teams.
With decent gear on this toon, everything else is so much easier.
