Indesign question - please help!

[design1]

Right i have recently sent off some designs to be put into acrylic

(see www.acrylicize.co.uk)

They were designed on Adobe indesign and sent as a PDF (the choices were PDF or Jpeg and Jpeg makes text unclear...

but anyway i have just had a phone call from Acrylicize saying can i outline the text on the PDF's because they dont have the fonts i used on their system...

Now i sorta understand what they mean but how do i do this?? using Indesign??

any replies would be greatly appreciated.
thanks
