Hire a data team with 282 verified reviews
Four ways to start, same team on the other end. Book directly for larger or ongoing work, or use a freelance platform if you would rather have escrow and dispute protection on a first project.
How do I hire The Data Collection?
Book directly at thedatacollection.com/contact/ for the widest scope and no platform commission, or order through Fiverr (4.8★, 282 reviews) if you prefer escrow and dispute protection. We also take work via LinkedIn for enterprise engagements and Legiit for SEO-related data projects. Same team, same process, same one-business-hour response either way.

FAQ
Before you hire
Who is the best data cleaning expert on Fiverr?
We are not going to claim a title nobody awards. What we can show is the record: 282 reviews at 4.8 stars, 269 of them five-star, 450 orders completed since June 2020, and an average first response of one business hour. Our CRM and data cleaning gig alone holds 237 reviews with zero one-star ratings. Judge that against anyone.
Should I hire you on Fiverr or book directly?
Either works and the delivery is identical. Fiverr suits you if you want platform escrow, dispute protection and a familiar checkout — worth it for a first project with a new supplier. Booking directly suits larger or ongoing work: wider scope, a named account contact, and no 20% platform commission sitting between us.
What is your Fiverr seller level?
Level 1, with 4.8 stars across 282 reviews. Levels move with recent order volume and response metrics rather than total track record, so we would rather you looked at the review count and the five-star ratio than the badge.
Can I see your work before ordering?
Yes. Ask for a sample and we will clean a small batch of your actual data so you can inspect the output before committing to anything. Most disputes come from mismatched expectations, and a sample removes that entirely.
Do you sign NDAs for freelance-platform work?
Yes, on request, before you share a single record. We sign as Sowrav Chowdhury trading as The Data Collection. Your data is deleted after project approval.
What is your average response time?
One business hour, verified across 282 completed orders. Sowrav reads every enquiry personally — you are not writing to an account manager.

Every gig below is delivered by the same team, to the same standard, with the same one-business-hour response. Ordering through Fiverr gives you escrow and dispute protection, which is sensible on a first project. For work over roughly $500, booking directly avoids the platform commission.
