well firstly is:Making amulets from gems
u will need about 10-20k go to bob in lumbridge and buy chisel and gems click chisel on gems and you will make amulets then sell them to shop keeper in lumbridge castle then repeat
Secondly:Killing Black demons
teleport to taverly dungeon turn right into the pipe. turn right again down a alley then when u see chaos dwarfs turn right and you will be at black demons. Black demons drop rune armour most of the time and they dont deal much damage on you:)
thirdly:thieving
this is quite good money just telport lumbridge and steal from the stalls
cake=1k
slik=2k
gold rings=3k
and so on just get a full bag then sell at shop keeper
lastly:abby whips
you will need 85 slayer and 80+combat
just teleport to slayer tower and go to the very top and kill the abbysal demons it will take a while for them to drop but they are worth 10-20m
Hope this guide helps,if you really need money quick i shall try and give you some
