Raiser's Edge Donor Data Merge

I’m looking for someone who knows Raiser’s Edge NXT inside-out to help me get a client's donor data under control. The focus is donor management, and the immediate task is to combine records coming from several external spreadsheets and systems into a single, clean database. Estimated 50K+ records

Here’s what I need done:
• Import and merge data from multiple sources into Raiser’s EdgeNXT.
• Validate each record, correct obvious errors, and perform basic data cleansing (names, addresses, email formats, etc.).
• Eliminate duplicates so every supporter ends up with one accurate master record.
- Identify outliers which need further validation
• Provide a brief walkthrough or set of notes so I can repeat the process for future imports.

This is a contained assignment—no full-scale segmentation or reporting required right now—just a solid, reliable merge and cleanup so I can move forward with confidence. If you have hands-on experience with the RE import tool, global changes, or similar utilities, let me know how you’d tackle the job and how soon you could deliver a cleaned database ready for everyday use.
