まず、"スムーズに行かない"についてですが、
私たち側(日本側)の打ち合わせや仕事の進行がスムーズに行かずに、
あなたを待たせてしまっていることを申し訳なく思っています。
また、今現在、貴社と協力体制を取れるメーカーは見つかっていません(話し合い中)。
よってギターの設計図など、御社の特許に関わる物は、まだ送らないでください。
あなたのリクエストを実現するように最善を尽くしていますのでご理解ください。
Now, I'm contacting you using a translation platform.
First, about "It's not going smoothly", we (in Japan) are very sorry to have kept you waiting because our discussions and work are not going smoothly.
Also, at this moment, we haven't found any maker which can cooperate with your company (under discussion).
Therefore, please do not send us anything relating to your patent such as a drawing of guitar yet.
We are doing our best to meet your request.
Your understanding would be highly appreciated.
I had it translated as follows.
Firstly, regarding the matter which "does not go smoothly", we are afraid to have kept you waiting because internal meeting at our side (Japan side) and process did not go smoothly.
Also, at the moment we have not found any manufacturer which will be able to cooperate with you (we are under discussion). Therefore, please do not send anything involving your patent such as guitar design etc.
We appreciate your understanding as we are putting our fullest effort to realize your requests.
I will contact you after I get this translated.
First of all, about "not going smoothly".
I am sorry that we are keeping you waiting because of
our side (Japan side) meeting and task progress is not going smoothly.
Currently, we have not found a manufacturer who can work with you. (In negotiation)
Therefore, please do not send anything that involves your patent such as the drawings of the guitars, etc.
We are working very hard to actualize your request.
Thank you for your understanding.
