assets valuation system

I need a simple system for valuation of assets in existing companies it needs to hold unlimited different assets (machines or inventory) including pictures of it. need to be able to use on a computer or ipad. 1. you make a few pictures of the machine with your ipad. 2. a pop up asking for a few details of the machine or asset (production date, machine number, new price, estimated price) 3. everything should be in one sheet where all the input is visable, here you can also click on the number and see all the pictures which belong to the machine/asset. 4. it must be possible to change value or prices in the overview. 5. also in a seperate photbook all info and pictures must be possible to see (multiple pictures possible to see behind every picture)
