Plugin Request SilksSpawner addon.

Okay so. I run a small survival server. I would like for my players to be able to buy and sell the spawners that they mine with SilkSpawners using signs in our shops. I have tried doing this with essentials, but when you use the spawner ID, it just gives you the default spawner. I know that spawner types aren't stored in the inventory. Part of this plugin could be changing it so that spawners IDs and types ARE stored while in inventory and not just when they are placed. I think this plugin would be VERY beneficial to mine and HUNDREDS if not THOUSANDS of other servers. I have found one plugin that would allow for buying but not selling spawners, and it is a paid plugin. So I'd have to cough up real life cash for a plugin that only does HALF of what I need it to do; Certainly NOT worth it. Lastly, I need it to work with 1.8.3 CraftBukkit/Spigot (lastest build)

Suggested Features:
-Compatibility with Essentials, SilkSpawners, and Spigot/CraftBukkit 1.8.3
-Buy and Sell Signs that match the style of Essentials Signs.
-Force spawners to be stored with their mob type in inventories.

Suggested Sign Format:
[Buy]
Number
Mob Spawner Name
Price

[Sell]
Number
Mob Spawner Name
Price

Kinda like the the essentails signs one but you can write the name of the spawner for example...
[buy] or [sell] like this [Buy]
[number of spawners] 1
[mob name] IgSpawner
$100,000 $100,00

Ig stands for IronGolem
