Accounting & Budgeting Spreadsheets.

Our budgeting & Accounting spreadsheets are not working as well as they should be. I would like an **accounting / excel pro** to go over these and make them into a more accurate system (the accounting one is okay but the budgeting one definitely needs improvement. I would also like to try and remove error as much as possible. For example we work with multiple currencies which can cause errors. I want to be able to have clearer reports & a clearer idea of the position of our business at any given time. I would like the job completed in 1 week. Thanks
