Tabulate Sales contest Winners.

i'm running a sales contest and need to have someone group certain 'teams' off people together and tally up how many sales they have made and then sort them by who's made the most sales to the least sales. we are also doing a daily speed contest so you'll need to show what team is the first to reach 5, 10, 25 and 50 sales. for that day (seperate daily sales spreadsheet) I will give you the list of usernames that need to be grouped together and the sales data at the end of the day and it will need to be processed and ready for me by the morning. I will need this done everyday until july 21st. possibly longer depending on what other contests we decide to run. if you need a sample of the data please let me know and i'll get it to you privately to make sure you're able to do the job. thank you. --Corey
