Bar charts drawing in illustrator

I have 40-50 bar charts currently created in Excel that need redrawing as hi-res charts ready for publication. I am looking for these charts to be redrawn in Illustrator as eps files with a fairly quick turnaround. Please quote on the basis of 50 charts for the entire job. I will supply our house fonts and current excel charts. In your reply, please let me know when you can get this job done by.
