How to get a skillcape

Hello RuneScape people! You're probably thinking... how do I get a skillcape really quickly and easily? Well, I have a way for you to do this without any cheating or hacks. There are two skillcapes that are done this way, and they cost primarily little for a mid lvl 60s person.
Skillcape of Cooking
Yes, this is the easiest one only needing 600K. First of all, you should get your cooking to 40 by cooking trouts, then salmon, then tuna. When it gets to 40, buy 73,000 buckets (575K). Fill all these buckets up with milk (the very long part), and then store them in the bank. Then, buy 73,000 pots (73K). Pick 73,000 pieces of grain and get pots of flour and store them in your bank. Now, go get 73,000 eggs and put those in your bank as well. Now buy 50 cake tins. You mix all the ingredients together (eggs, pots of flour, and milk) into the cake tin, then use it on a range (this will give you 180xp). Every time you finish an inventory, eat the cake (or else you would have to buy 73,000 cake tins). Repeat this 73,000 times. This will probably take you one and a half months, but if you stick to it, you will have a skillcape.
Skillcape of Firemaking
The instructions here are actually very simple. Go to the grand exchange and buy 144,000 willow logs (18gp each or 2.6mill total, then burn them. THAT'S IT!
