Convert paper floor sketch plan into pdf as build with measurements

I'm looking for someone to convert a floor plan sketch that I currently have in pdf form into a pdf document with exact measurements. The original document is a pdf - I don't have any other images I would like included in the pdf and I don't need the sketch to be used for exact measurements. Rather, I just need the floor plan to be converted into a pdf document with measurements. If you think you can help, please let me know. Thanks!
