create pdf with fill in forms from excel

Hi,

I am trying to convert an excel spreadsheet to pdf but would need to have around 4 field which should become fill-in fields when converted to PDF, meaning that the enduser would be able enter some text into these fields and then save the PDF.

Any clues how I best go about this? I dont want to go for the 500 USD adobe acrobat solution if possible. Office 2007 at work here, but should be operated in an 2003 environment.

Any suggestions are welcome!
