Hi sir, Thank you for reading my proposal.
Yes I can do it. I can create a C# windows application to host your spreadsheet or I can code all your spreadsheet functionality into a windows application.
I'm a professional client application developer with wide experience in, C# and database programming, PHP, Excel, Web scraping and automation.
Please send me a part of your spreadsheet and I'll prepare a demo for you just to make sure that I can do the job the way you like, then if you are 100% satisfied accept my bid.
By the way, I don't take initial payment, I take all the money after my customer is 100% satisfied.
So, please let me know if you are interested.
Best regards, Abdou.
