Hello.
I am a Japanese teacher who live in DT.
I am looking for a nice student who is really interested in Japanese.
Any ages are wonderful!! I can teach Japanese to kids,too.
(I have a experience to take care of kids for long time)

$5/hour(if you want to study an academic Japanese, a bit higher,but still under $10/hour!)

Please give a message,I am looking forward to yours.

*I do NOT need a person who is looking for JAPANESE GIRL.

正しくは
for a long time
live downtown　です

英文を見てると1文1文が短いし簡潔すぎて
まるで子供が使う英語のようです。
まずは英語からって思ってしまいました。
そしてこのｻｲﾄは基本日本人が使うｻｲﾄなので
ｸﾚｲｸﾞﾘｽﾄに載せたほうが早く見つけることができますよ。 　

投稿者さんは文法を直してもらうために投稿したわけではないと思いますが、少しでも正しい英語を使ってもらいたいので少し口を挟ませてください。私だったらこのような文章で紹介します：

I am a Japanese teacher living downtown.

I am looking to teach students who are interested in learning Japanese.

Anyone interested in Japanese, regardless of the age, is welcomed.

I actually have plenty of experience with taking care of kids, so I’m willing to teach them as well.

$5 per hour(I can teach you academic Japanese for extra $5)

Serious person only( this is not where you can find romance with a Japanese girl)

Feel free to contact me. I look forward to hearing from you soon.
