Recommendation for an Immigration lawyer (PR application)

Hi, I am thinking of applying for Permanent Residency, and I already have a sponsor lined up on top of meeting other requirements through the Highly Skilled Professional route (one year). My Japanese isn't great, so I thought I would engage the service of a lawyer to get this done. Can someone recommend a good and economical lawyer in Osaka? DM ing is also OK. よろしくお願いします。
