Hi, I'm a Delphi developer with more than 30 years of experience, I also have extensive experience developing MS Excel add-ins and ActiveX/COM objects (used by Excel and other MS Office applications). I'm sure I can help with your project. Your descriptions is not enough, so we certainly will need to further discuss your requirements.
If you think you may be interested in my service, please send me a message.
Best regards,
Marco García
