I've been walking around with the similar idea and also I do have (most of the) resources to make a project like this and the manpower to make it happen. However there are so many problems involved to make the server successfully.
Leveling
People these days who still play silkroad got used to leveling fast. Due the many private servers that are online they have the choice to enter a server were they can level up to the highest cap within 3 day. Or they can join the "original-look-alike" server and must farm+level for over 4+ months to reach level 80.
Now some might think that the solution is to make leveling a bit easier. Well no..
When you increase the level speed you also unwillingly increase the goldrate, the amount of goldbotters, the items for the last set, the alchemy rate. Basically when you make leveling easier, everything becomes different.
Silk price
The silk prices from isro might seem high, however that is also done with a reason. The less silk you get the harder things such as alchemy will become. When you can buy 30 immortals with just €10,- going above +5 on a sun item will be way cheaper and therefor easier to make +7 or higher. *well then you just change the silk prices like isro?*
Here we go again; when you do such thing. Nobody will ever donate for silk; why would you donate 50 euro for 2.000 silk. When you get 20.000 silk for the same price?
So therefor the money you gain isn't support the server and you will go offline eventually.
Free silk
One of the most stupid feature that has EVER been created is free silk. I've no idea what fu**** came up with that. What's up with free silk per hour, vote for silk? The reason silk has been introduced in game (and in other games) is so the servers can keep on running. So when you add this feature the server isn't going to last for long and it wont be like the oldskool times.
If you don't; people complain about pay2win and you wont gain any users at all.
Also donations will pay for the person who invest his time in it. If you go to the supermarket and buy a pack of cookies. You don't pay for the cookies only, you pay for the person who makes it possible for you to grab them. You pay for the location, the building, the safety investigation in the cookies so you don't get sick from a parasite in a cookie. And therefor it's possible for a supermarket to keep on selling their products.
Time == money.
Everything together: Gold, silk items, alchemy, old tablet system, trading rates, avaters (luck + premium), Sox drops
To make a long story short, all those things need to be original and therefor it's just not possible.
Even if you find yourself a millionaire which can easily support the server. He wouldn't even try since he became millionaire probably because he knows business and then we are back to joymax. And that's also because there might be a chance my server would fail simply because the thing I do for a living is business.
I do like the idea, and maybe if the other private server rates and shit didn't exist. I'd be sure it would work out.
