I've been through a similar route with our small CA team. What helped us was focusing first on U.S.-based freelancer platforms like Upwork and Alignable to build initial trust, once we had 2-3 long-term clients, word-of-mouth started working.

Also, cold outreach doesn’t work well unless you have a solid U.S. referral or case study. Try offering a pilot month at a reduced rate, that usually gets attention without underpricing your entire practice.
