値段的には厳しいかもしれませんが、一応調べてくれると嬉しいです。
ご迷惑をおかけしますがお返事ください。
Thanks for the reply. It seems like I forgot to mention it in my last email. I'm sorry about that. I'll resend what I said.
The price might not be what you expect, but I'd be more than happy if you looked into it.
Thank you so much for your help and I look forward to hearing from you.
