Add 2 new columns (fields) to an existing crystal report with SQL backend

Add 2 new columns (fields) to 2 existing crystal reports with a SQL backend. I have more reports that need to be modified. I would like to hire someone who can finish all the work very quickly. Work fast and clean and I will give you more reports to change or fix every week. Each of the changes usually take me only 10 to 15 minutes to complete. It should take less than 2 hours for an intermediate SQL developer to finish this work.
