Hi,
My name is Jeremy, and my Japanese partner and I are a duo Japanese-English translation team that provides all kinds of language services. We saw your posting, and we'd like to offer our services to you.
After leaving our jobs to form our own group, we've been blessed with the opportunity to work with many companies including those from the UK. With specific regard to your proposal, we actually just finished an assignment for another UK-based company looking to expand to Japan. You can find our work here: https://www.amazon.co.jp/s/ref=bl_dp_s_web_0?ie=UTF8&search-alias=aps&field-keywords=Bathing+Bunnies%E5%85%A5%E6%B5%B4%E3%83%90%E3%83%8B%E3%83%BC
We also have experience optimizing keywords to fit into the Amazon marketplace, so rest assured you're not just getting a standard translation, you're getting the full package with us.
Our standard rate is 0.10 GBP/word, but we can be flexible with this pricing depending on the size of the project. We can discuss price specifics if you're interested in working with us.
Thanks for reading, and I hope you consider us for your Amazon venture!
Jeremy and Marie
