With that you have, use it towards fletching. You can make money off it only by cutting your own logs though, but if you don't mind 99 fletch as a cost then just buy some maple/yew logs, cut them, sell unstrung bows, repeat until you get low on logs in which case you just buy more For rc to make money, I would just use abyss to make cosmics (since you have double cosmics) until you can make deaths. Then make deaths. I would also keep up with MTK and farming herbs on the side. Maybe the fastest way for you to make money right away is to collect herb seconds. One way is to farm limpwurt roots in addition to herbs. I would collect blue dragon scales since you have 70 agility for the shortcut, and can just tele back to falador. I've heard scales can be 650k to 800k per hour depending on prices. White berries near Lletya are good too if you have a lot of teleport crystals. And I know you said no slayer, but tbh, I've made more money off clue scrolls doing slayer tasks than anything else but rune mining. Plus if you get to 78 before the new monster is released, then you can have a chance at a new drop which will sell for lots at first even if it is a horrible item.
