I need help with an interactive 3D model for PDF but am not sure I am in the right place!

Hi,

I am trying to design an e brochure (flip book style) that can also be attached as a pdf file. I would like one of the pages within the flip book to have a an interactive Model of a simple pathway and some icons( feels rather rudimentary and a little inadequate compared to other requests on here ) . The web designer I have hired is saying he does not think this is possible and if it is it will cost significantly more. I have done some amateur investigating and found blender. Can anybody on here design and make an interactive model for PDF for me to use in my brochure? I am willing to pay. xx This seems a very simple task compared to the others on here and I am a little embarrassed.
