Update Prices in AI File

I have an existing Adobe Illustrator file that simply needs its current prices revised—Deletion of of text boxes and small wording adjustments and swap of the old figures for the new ones while keeping every element of the layout, typography, and colour palette intact. All text is already on editable layers, so the task is purely a quick typographic update.

Once the figures are changed, I’ll need the file returned to me in its original .ai format along with a print-ready PDF for immediate use.

Please be comfortable working in Illustrator and able to turn this around promptly; accuracy is more important than speed, but I’m hoping for both.
