Can do a C++ or VB project for you

Quality: perfect
Time scope: just in time
Rates: $20/h

Give me an estimate on how long you think it would take to do the following, with brief explanation of how you would do it.

1) Import 5 text files into staging tables in a SQL Server database.

2) Compare data in staging tables to 5 other corresponding tables.

3) If record exists in its corresponding table, update the record, If not add a new record.

I get updates every month in txt format, some comma delimited some tab delimited, that I need an application to import these files into my staging tables and then update any existing records or add any new records.
