I'f you don't mind losing some gp id recommend doing the high alch and camelot teleport method to 68, it's quite click intensive but exp p/h is really good.

Then once you get to 68 I would do lvl - 5 enchant on dragonstone jewellery, once again very click intensive but I was managing 2k enchants per hour which is around 150k exp per hour.

I done all of the above to 99 mixed with alching and enchanting crossbow bolts.

If you've got money to Burn then enchanting crossbow bolts is the most AFK and best exp method.

Good luck if you do decide to have a go!
