Hello there,
7 pages with the functionality you are asking for will take time and adjustments.
i am NOT trying to convince you this can be done in a day or two, and in order to make all pages work without problems...
i'd create the pages in a layout program (InDesign that would be) and then add/adjust and program the functionality in Adobe Acrobat.
One thing, though, that you also have to know is, and I AM telling you this, that there are certain restrictions with saving/emailing filled .pdf's, just telling you so you're aware of this and not surprised and/or wondering
thank you
(some samples that I created you can view at - replace the 3 "DOT" with an actual . - wwwDOTa1retouchingDOTcom/fillable_pdf_formsDOThtml)
