Looking for Excel expert to create a summary of Excel tabs

Looking for an Excel spreadsheet expert to accurately create a summary of Excel tabs.

This summary will be of a number of tabs that already contain information such as:

- Products
- SKU by customer
- Costs etc.

We would require for you to be able to create another tab and summarise all of the information in these tabs.

If you are confident that you have a high knowledge of Excel and have done something similar to this before, please send a proposal.

Please also send similar work you've previously done along with your proposal.

Thanks.
