Data Sorter / Data Entry

We are a event ticketing software company. Users of our app can form groups and our job is to ensure that all groups are sitting together.

We have CSV reports generated for:
- Groups and group sizes
- Seats available in a venue

We have an algorithm that assigns seats to groups, but sometimes seats can accidentally be split up. ie: a group of 4 might get seats that are not next to each other. Our system will highlight groups that are split up.

We are looking to hire a data entry/analyzer expert who can help identify where seats are out of place (its not that difficult), and if you find any, refer back to the available pool of seats and update the seat number for the out of place group.

This person should be a excel/spreadsheet wizard who we can rely on to achieve both accuracy and speed.
