Advanced Development of multiple sheet Excel quoting system.

We have an Excel quoting system with multiple sheets and many lookup tables. We need the spreadsheet designed to do the following: 1. Save a generated quote with an auto-generated quote number and date. 2. Format this quote as a printable PDF with our company log. 3. When a quote is retrieved and amended it is automatically saved as a new quote with a new quote number. 4. When a customer accepts a quote the spreadsheet will generate: a) factory build instructions for the units in the quote b) an editable dispatch note with customer address. Currently the spreadsheet generates the quote and exports as a PDF but doesn't save the quote. So every new quote is the only one in the system. 1. We require a design brief on how this can be achieved and if this is satisfactory, we will then 2. employ you to implement the design. 3. All copyright for this work will remain with our company. Examples of previous work with Excel will strengthen your bid. Please briefly outline concetanation in your bid. Thank you
