for work i use PDF's that have typeable sections for me to fill out and then send to the client to agree on the contract and then they print sign and return to me. does anyone know an app that would allow me to type on a PDF that has fields?

i keep all my work files on my iDisk so i can get them from anywhere and use GoodReader to connect which works great but the typing on the PDF has me stumped.

thanks for any help
