Upgrade 2 Magento Stores

Hello, We own two Magento stores that need to be upgraded to the latest stable version. Updated template files will be provided and should make the project much easier. Both stores have a few custom modules which were installed & developed by our in-house programmer which is no longer available. You will have to upgrade the websites and make whatever changes necessary for the custom code to work perfectly with the new updates. The sites must look and work as they did before the upgrade. We are looking to complete this project as soon as possible and price is an issue so please place your best bids right away. Thanks
