Japanese surname phonetic transcription (IPA)

I have 5000 Japanese surnames.
I need someone with linguistic knowledge to phonetically transcribe them using the IPA standard. (IPA is international phonetic alphabet.)

For example:
Kusa Kan --> cǎojiān
Kusa Suga jinmei --> cǎojiānrénmìng

Please do not bid if you are not a native Japanese speaker.
A degree in literature or linguistics can be an asset.
