Some conditional logic on list items

Hi,
I like to get the following thing to work:
I have a order form. This form is used basicly for orders. With a checkbox checked (“this is a quote”), the order turns in a quote with some fields hidden and with another PDF attached.
Now, 4 topics:
#A the field 233 is this checkbox. empty = state “order”, clicked = state “quote”
#B Hide field value in list column «Total»: If it’s a quote, hide the value.
#C Change field entry if it’s a quote: If state is “order” > “Reorder”, else “Order”
#D Change Link to PDF if it’s a quote: link to quote-PDF instead of order-PDF. If not possible, just hide the order-PDF link.

For better understanding see also my screenshot:

If your help is behind the usual support task, I’m also willing to hire you for this customizations…

Thank you for your feedback!
Best, Marcel
