1. Begging will get you banned. 2. Good way and helps support the server. 3. Complaining is unappreciated. 4. I vote every day and get around 1,000 rupees daily. If he's in an economical crisis, how could he afford to make an iron farm? I have 180k, but I have plans for a grinder might take me a few weeks to do and will basically run me broke, but it might be worth it.
It can be made with dirt, water,lava, doors, and a couple of villagers that you can breed EXTREMELY quickly if you know what you're doing.
I don't reveal all my ways to make money, because obviously if I did, then the opportunities would disappear. I would recommend the following: 1) Voting - takes about 3 minutes and if you average out the rewards and vote every 12-13 hours, you get about 3-4k/day. 2) Shearing sheep - make hundreds of rupees per hour. I pay 70r/stack. You don't even need an axe! I have links to all the sheep farms on SMP9 at /v 19500 (in the wool section). 3) Chopping wood - due to how easy it is and how anyone can start a tree farm and get lots of money. I buy every type of wood for 120r/stack (or more), you can make thousands per hour. 4) Mining diamonds - I have a large efficient mine and my miners make about 6-11k/hr. You need a 12k deposit though, so it takes a while to get that. If you choose to mine on your own and bring your stuff to shops, you can usually make 3-7k/hr. 5) Mining quartz - Quartz fetches insane prices right now due to the fact that you can only get it in the wasteland and it's the most desired building material. I pay 2k/stack, and you can usually get about 5 of those per hour if you are skilled, plus you can get netherrack and glowstone at the same time.
Hey a diamond axe costs about 240r... Whereas shears are 9r... I mean you could use a stone axe or an iron axe, but it's more efficient to shear at that point I think.
Go mining, sell ores to malls like mine, there are lots around then go mining again try not spend so much. Voting is always good but do other things also, a tree farm is always good also as mentioned.
