Quotation Plugin

Hello,

I’m wondering if anyone can point me to the best plugin for my requirements?

Requirements:

A quotation platform for the Sales Team to login to and produce quotes for clients
To be able to generate a quote from the information provided in a PDF format (or Word Format)
The quotes will be quite complex as it’s for bespoke telephone and CCTV systems.
Such as, when a certain amount of phones are added a certain card will need to be automatically added, and many more.

Is there a plugin like this for WordPress? = If not, any other suggestions?

Thanks in advance!
