Meta / Instagram Username Acquisition Expert Wanted

I’m looking for someone with proven experience obtaining specific Instagram usernames to help me acquire @daalvi. I have an established Canadian business under the Daalvi name, an official website, business/GST registration, Google Business Profile, YouTube presence with millions of views, and matching accounts on other platforms. The current @daalvi account is small but still active.

I’ve already tried Meta’s standard trademark form, so I’m looking for someone with real experience and a legitimate strategy or alternative ways.

Please briefly answer:
• Have you successfully handled a similar Instagram username case before?
• What method would you use for @daalvi?
• How long could it realistically take?
• How confident are you about this project?
