Well then yes, cooking would be decently easy with a few mils loss. Fletching, I'm not so sure, I got 99 when I was still able to profit from it. What I'll suggest is though, level range up, buy some decent gear and level defense. Now depending on how you do this, you can end up with high def/range with no losses also. Then you should begin dking/gwd for money and get that cash up so you can dump 85m on herblore or 100m on prayer. The best thing you can do in this situation is to level the skills that are going to help you boss hunt to make more money, more money means more effcient training. If you don't like that advice, level cooking for sure since that's the cheapest. If you have the patience for firemaking, then by all means, it should only set you back 3-6m, and then fletching. I also recommend thieving since it's huge xp/hr and hunter because the profit you'll make off it is way to immense not to, to be honest.
