Looking for Japanese language lessons

Hello,

I am looking for someone who would be willing to teach me and potentially 2 more of my friends Japanese language (speaking and reading). I have always wanted to learn Japanese and now I am planning to visit Japan next year (Spring 2018) and I would like to be able to communicate when I am there.

Ideally I would like to have lessons once a week. I found that most people charge £20 per 1 hour which is a bit too much for me to pay every week, that is why I wonder if someone would be willing to do a 1.5 hour class once a week for £30 for 3 people? I am looking at having classes until I go to Japan so that is potentially one whole year of classes if someone would be willing to agree to this. I live in Beckenham which is half an hour train journey from Charing Cross or Victoria stations. I am also happy to meet in central London - for example, at the South Bank Centre (the 5th floor is free to use by the public).

Thank you for taking the time to read my message and I hope to hear from someone.

Best regards,
Izabela
