Why one herb level? Because you need 85 herblore for super anti fires. They are pretty much required for effective killing of QBD. You can get +5 herblore boost with spicy stews(brown). But yeah, since you can't afford and don't have the stats for drygores, you should first hit dungeoneering 85 or more. Get dual chaotic rapiers, then you can also camp frost dragons. They are very good money with your stats. Duo bandos is also a possibility but this is not a very good gp/h method. Right. Didn't consider spicy stews and thanks for the input.
