Macro To Generate New Quote

What I require is the macro code to achieve the following:-

Cells A2, B2 and C2 will be completed manually, however, when a new quotation is required the user must enter a new Control Reference Number in cell E2 and then press the Generate button.

Once pressed the Macro behind the button will generate the following :-

(a) Quote number underneath the last one in column 'A'

(b) Change Ref underneath the last one in column 'B' (this was the ref number input above in E2)

(c) today’s date underneath the last one in column 'C'

(d) a blank Quote Tab i.e. labelled the next number in the sequence i.e. Quote 2, Quote 3 etc which should be created copying the Template Tab

N.B. the total number of Quotes in any one work book should be a maximum of 30 so some form of checking would be required.
