Creating Business Cards using GIMP

Create business cards for four new employees using our existing GIMP template.
Make text changes to existing 6 business cards.
Export as CMYK TIFF images ready to send to print.
Final to be saved as GIMP file.

Must be proficient in GIMP.

The four new employees will need to have head shots touched up and backgrounds removed for each of three images (looking left, right and center) so 12 images total.

Please respond with quote and examples of photo retouching and background removal.

Thanks
Howard
