Job: create model

Hello I would like to model ticket models (entities) for my personal addons which adds numerous currencies for example (pound, rupee, euros, lira ......) so that when I drop a currency like euros it puts a euro note. I would also like to have several models per currency for example in euros I would like the 5, 10, 20, 50, 100, 200, 500 note. I would like it to be more realistic:

drop 1000 a bundle of 20 notes

drop 5000 a bundle of 200 notes

etc.. this is an example
