Request feedback on SAMURAI IMMIGRATION LAW FIRM

Hello, folks!
I am looking for feedback on your experiences working with Samurai Immigration Law firm. I need to switch from my student visa into the ESHIS visa. However, I am applying via an unconvential route as a freelance worker (not part-time or full-time). And, I have checked with *several* lawyers (行政書士, Gyōsei shoshi) who were recommended in older posts in the group. But, they've all been incompatible — either the lawyers are not taking on new candidates, or they are refusing to work on my case because mine sounds "complicated" (their words), or their fees are insanely high (40,000 yen for a consultation!)

I came across the Samurai Immigration guys on the internet (link: https://samurai-law.com/en/index.html) and I understand they have a large team of lawyers, i.e., more ability to take on complex cases. However, given my very underwhelming experience with lawyers so far, I wanted to check with you if anybody here had any positive/ or negative experiences working with them?

Thank you so much for your time!
