Ok heres how I made millions. when I was only about lvl 20 I started fishing. that wasn't how I Hit real serious big time cash but it had multiple benefits - i.e. free food. I was already lvl 10 in fishing which most are at least. Iwent straight to draynor just behind the bank. There I fished for an hour or so - until I became level 20. After that I headed to barbarian village. within 2 - 3 hours Iwas believe it or not ready to fish some lobsters. 4 hours (give or take a half hour) and Iwas fishing lobsters. Iwent to karamja to the port there and fished them - it started off slow work but Igot better and better fishing them faster and faster.
I was never fond of cooking but thankfully I found a buyer who baught them raw for 200gp each. I made a good bit off him - I fished hard for a week straight and traded 1000 lobs for 200k. not bad but it got tiring. by that time I was well over 50 fishing without ever meaning to be and so I started on swordfish. just like the lobsters I did them from time to time - in between quests and training and my buyer very graciously offered to buy them raw too. I was stronger and rising all the time by that time though, and so Igot my cooking from 30 to 45 quickly and easily (I recommend cooking in the guild beside varrock or just cooking tuna/fish) and next thing I knew Iwas there with 200 cooked swordsish and 53 cooking.
I became a member and put the swordies to good use - occasionally fishing a few more (rarely burning them at this stage) and my good cooking lvl became very handy exceptionally so in the members world. after membership I was tired of fishing. I had 30 mining and smithing and so I took them up and worked on them. at the start it was absolutely terrible. I worked like a mule for a month getting coal iron silver then smithed them all up into bars and made them into swords ect. and got terrible money because I was limited in what I could make. however after I made them all into things I was excited because I was lvl 52 mining and
45 smithing.
a bit more work and I could make mithril. and so I worked thirsty for that crucial time when I was smithing those mithril bars, all the time watching others mining mithril with envy. then it finally came. I had about a thousand coal in the bank - occasionally i'd take a few out and get some money but I liked looking at the hundreds of them there in the bank, so I mined only a hundred mithril ores - no big deal, smithed them (about 2 hours max for mining and smithing them) and there I was with 100k. I kept making and making them and now at lvl 63 smithing ive started making things out of them, even more cash. if you want some good places for mining coal or mithril, I found some brilliant places. for coal (near a bank) go straight to edgeville. there, go to the room where the coffins are.
in the room south of it, go to the trapdoor to the southeast corner. once inside head due north, follow the path and dont stray or you'll get lost. keep going north until you come to a room with a gate (most usually closed) to the east. open it and continue until you get to a place which warns you of the wilderness which is north of where you are.
continue east then south past the zombies and skeletons in the tunnels until you get to the brilliant area with plenty of coal. I know it sounds like a long way to go reading this but it is surprisingly short. keep at it until you get to 60 mining and go to the guild. even more coal. for mithril you must have completed dragon slayer. on the island (accessible through karamja) there are plenty of mithril rocks. if you have not done dragon slayer, there is a mithril rock in the area of coal which I told you about. ruffly for every 4 coal you mine one mith should appear giving you enough. Thats all.. peace out
