Shop Costs as Items for VX Ace

Hey everyone, this is the first time I've needed to ask the forum anything. I hope this is the right place to ask this as it isn't just about either scrips or events.

I'm faced with a bit of a conundrum while making my game. You see I want there to be a shop that 'sells' weapons and armor by taking items and money off of you.

For example; to obtain the Iron Greatsword you have to pay 5000 gold and give 5 Iron Ore's where Iron Ore is an Item that can be obtained by mining or whatever.  Basically when you go into this shop it's price is "5000G, 5x Iron Ore".

I haven't been able to find any scripts that relate to this, the closest I came to finding was Yanfly's Common Event Shop however I'd need to make a common event for each piece of armor and every weapon in the game, and I don't really want that. 

I don't want to really event it either. Because then it'll become an endless chain of Conditional Branches for each item that has a cost more complex than 5000g and 5 Iron ore. Plus it doesn't have the cool shop screen.

For those of you who have played Monster Hunter you know exactly what I'm talking about.

Any suggestions? Anyway, thank you in advance.

You could use a crafting system like this:
