Convert PDF/JPEG files to DWG drawings

I'm looking for a freelancer with excellent CAD skills. Accuracy is one of the most important requirements. The task is to create CAD drawings basing on the PDF and JPEG pictures I provide. Floor plans of residential buildings, factories, hospitals are among those files. I need exact scale, good looking, readable drawings with all the details. In another words, you should be able to create the plans and structural schemes from the beginning till the complete CAD drawing. The file should be a DWG file possible to be corrected, edited, printed later. It is a fixed price job. If I'm satisfied with your work, communication, I would be glad to provide you with more assignments later. There are lots of files that need to be converted.
