Does anyone know of any software that would take a standard greeting card - A4 folded twice to make four sides that you print and post - and convert it to something that can be emailed?

I have programmes that I make my cards in (CorelDraw and Microsoft Publisher), but if I export them to pdf the four pages (front, centre left, centre right, and back) are exported out of order, two pages to a "page", and with the two central pages upside down.

Is there a programme that will create your own "e-card" that is completely customisable, that allows the recipient to click on each page (or an arrow at the side) and, in effect, turn the page?

Thank you.
