Hello sir, Thank you for reading my proposal.
I'm a professional client application developer, and I have wide experience with C#, Excel and database programming, Web scraping and automation.
I suggest that you send me 10 or 15 files 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.
