I propose to undertake the task of updating your clients' MS Access 2003 databases to meet the specified requirements within the given timeline. Leveraging my expertise as an MS Access Developer, I will meticulously update the Queries, Forms, Modules, Reports, and Macros to fulfill the outlined objectives, including the reconciliation of Bank, Customer, Vendor, and other Accounts (A), and addressing "Record Deleted" errors (B). Upon completion, I will seamlessly convert the databases to MS Access 2007 (C), followed by thorough testing and subsequent conversion to MS Access 2010 (D). The fee for this comprehensive service is 250CAD, with the project expected to conclude within a week, subject to the project's complexity. Upon completion, I will provide the necessary documentation and support to ensure smooth transition and operation of the updated databases.
