[REQUEST] Custom Villager Trading

Plugin category: Villagers

Suggested name: VillagerTrades

What I want: I would like a plugin to where you trade a villager and your trade doesn't get canceled. Also another twist to it is only allow the villager to trade a certain amount of times. Say I trade the villager 3 times and that's the max, a 4th trade won't appear. I'm using http://dev.bukkit.org/bukkit-plugins/merchant/ so if the plugin could be compatible that'd be awesome.

Ideas for commands:
Infinite Trading: /vt infinite [trade number]
I apply this to the very first trade. (/vt infinite 1) Never can be canceled.
Certain Trade Number: /vt max [number of trades]
I apply this to a villager wanting 3 max trades. (/vt max 3) Only 3 trade windows will open.
NOTE: I am using http://dev.bukkit.org/bukkit-plugins/merchant/ (Cannot be like VillagerShop) (Actual Villager GUI/API)

Ideas for permissions:
Infinite Trading: vt.infinite
Certain Trade Number: vt.max
OP: vt.*

When I'd like it by: I am a very impatient person, but I can wait considering this is a request and no one has to do it if they don't want. This can be done whever.

Thank you for your time.

Is this even possible? If so how difficult is it to make w/compatibility of the Merchant Plugin from a scale to 1-10? Thanks for any reply.
