Different SKU for same book title, renting it & tracking the availability.

Hello,

I don't know this is the right place to ask it. I have to build a inventry for a library system. Where I will have different copies of same title, so I want to keep unique identifier for each copy and keep that as SKU for the item. I will have some other atributes too.

My all book will be listed even if no item of a title is in inventory, user can add it in his/her wishlist(my account) section. But when he try requesting the bundle( 2 items one time), only available title will be shown to him from the wish list.

At admin side I want the request to be listed and for each title available SKUs in select list. I will select one SKU & close the request & it will make that SKU unavailable from the inventry to be requested next time till I update this to be available.

You may think that why I am thinking to make this with Drupal commerce. Then the thing is, I have selling option too for the same products. That means a book can be bought or rented.

Any body can suggest me anything regarding this...like how it can be done with drupal commerce? Whether it can be done or not by available modules? If I get to code...how much things I am already having in this contributed module for this kind of system..

I am newbie to Drupal commerce so I am not able to figure it out..

Thanks
