3 hours of VS C# Help Needed

Interested in 3 hours of C# coding support in connection with a
cmd line app I need for checking/testing if a type of file is valid.
Below's example of a 1 line file I'll need tested and reported on:

"string...","string...","string...","string...", //use any string in the field

Above's a "File valid" example. Notice each of the 4 fields begins
with double quotes and ends with ", Notice no text between fields

abc"string...","string...","string...","string...",
"string...","string..."ghi,"string...","string...",
"string...","string...","string...","string...",kl
Above are 3 examples of "File corrupt" cases.

Name this FileTest.cs Usage: FileTest.exe filename
Print 1 of 4 statements after execution:

"Usage: FileTest.exe filename" //to print if one arg is not used
"File not found" //to print if file not found
"File valid" //to print if file is determined to be valid
"File corrupt" //to print if file is determined to be non-valid

Anyone who's very strong working with C# is welcome to contact
me to discuss this further. I'd like 3 hours of C# coding support
which includes writing above described cmd line app, as well as
some other 'minor' specs to be discussed.

Thank you in advance for your interest and your bid.

Best regards,
Grant
