There's guides for this on YouTube.
Arrows/bolts/darts are the fastest way to go. Some of them cost extremely much but reasonable options would be adamant bolts which are about 10 gp/exp
Bolts and darts both used to only be limited by how fast you could click. It used to be possible to get 1m xp/hour, but unfortunately Jagex changed that sometime last year.
As for the current speed of fletching: it's still one of the fastest skills, and 1-99 can realistically be achieved in under 125 hours. It's been a long time since I played, so I can't really help you with cost.
True. They aren't as fast now as they used to be but broads still yield 500-600k exp/h. It's also semi-afkable now though.
