Completing small clock-in and clock-out site.

I have a small clock-in and clock-out site where employees can start and stop their workdays. The site can show lists of hours for each employee for specific periods. And each employee has hourly rate, and extra charges that are valid for specific time periods and days. Then it can show salary notes for each employee. A programmer was making corrections and small additions to the site but had to cancel the remaining parts due to personal issues. I am looking for someone to make the final corrections. This must be made on the site: - Detection of weeks. (Every employee has defined a "Normal hourly rate", "Total weekly hours" and an "Extra weekly hours rate". When the employee works more than the "Total weekly hours" the salary note starts calculating the "Extra weekly hours rate" instead of the "Normal hourly rate". But right now it does not reset the week and start calculating "Normal hourly rates" when monday starts but just keeps calculating with "Extra weekly hours rate". This must be fixed so that a week is from monday to sunday and then a new week starts. - PDF print. (A PDF print of the salary note, which is a basic overview page) The site is made in PHP and MySQL. PLEASE DO NOT BID ON THIS PROJECT IF YOU CANNOT COMPLETE IT WITHIN 3 DAYS! PREFERABLY SOONER!
