Hello,
I'm working with Excel (developing also VBA programs) for 15 years and I'm a VBA and Excel trainer for 12+ years. As you can guess, I have done any kind of Excel work, for both training purposes and business.
It's not possible to say something on your project, without the project details. Please contact me to discuss it. Of course the given duration of 4 days is simply an estimation.
Looking forward to hear from you,
Kind regards,
Chriskerpini
