Microsoft Access Database Fix

I'm seeking an experienced Microsoft Access developer to troubleshoot and resolve data errors in an existing inventory database. These issues occur daily and need urgent attention. Organisation is a charity happy to pay a reasonable rate to resolve the problem and/or consider viable alternative like a reasonably priced off the shelf product.

Key Requirements:
- Expertise in Microsoft Access, particularly with corruption and data error resolution.
- Ability to diagnose and fix underlying issues causing frequent database corruption.
- Experience with inventory databases is a plus.
- Commitment to providing a stable and reliable database post-fix.

Please provide a detailed plan and relevant experience.
