US Trademark Attorney Needed for International (Croatia) Applicant

I am looking for a US-licensed trademark attorney to handle the trademark filing for my brand. I am based in Croatia (foreign-domiciled), so I require a US attorney to represent the application and serve as the correspondent as per USPTO rules. Scope of Work: Comprehensive Knockout Search: Perform a search for the brand name in Class 005 (Dietary Supplements) and Class 035 (Online Retail Services) to ensure the name is safe to use and whatever else necessary. Correspondent Services: Act as the attorney of record for the application. Requirements: Experience with USPTO filings for international/foreign-domiciled clients. I'd like to discuss this first before determining what the flat fee quote would be.
