Writting a letter to a Japanese host family

So i am currently trying to go on exchange in Japan next year and i have to write a letter for a potential host family. I really want to write the last part of it where i thank them in Japanese and therefore wanted to know if i can write it the way i've done.

(Thank you for your hospitality)

(My japanese is still not very good so im sorry if i make mistakes)
�킽�� �� �ɂق� �� �܂� �݂��キ �Ȃ̂� ���� �܂������� ������ ���߂Ȃ����B
(I want to study more japanese and will do my best to learn it)
���{��������Ƃׂ񂫂傤�������ł��B���͓��{��ׂ̂񂫂�A����΂�܂���B
(It look foward to seeing you it means a lot to me)

Thanks a lot in advance for helping me. It's so nice of you :)

- This sound like they have hosted you already (in the past) and you are thanking them later for all the kindness/hospitality they have extended to you. It will be next year, right? I will rephrase it to say �gThank you for being/offering to be a host family.
I would say:�@�z�X�g�t�@�~���[�����Ă�������Ƃ̂��ƁA���肪�Ƃ��������܂��B

(My japanese is still not very good so im sorry if i make mistakes)
�킽�� �� �ɂق� �� �܂� �݂��キ �Ȃ̂� ���� �܂������� ������ ���߂Ȃ����B
- Just a few typos on this one:
�킽�� �� �ɂق� �� �܂� �݂��キ �Ȃ̂ŁA���� �܂������� ������ ���߂�Ȃ����B
-

(I want to study more japanese and will do my best to learn it)
���{��������Ƃׂ񂫂傤�������ł��B���͓��{��ׂ̂񂫂�A����΂�܂���B
- Just one typo, and I am omitting the �� at the end of the sentence (I am sure you�fve added it for emphasis, but this can sound somewhat overbearing.)
���{��������Ƃׂ񂫂傤�������ł��B���͓��{��ׂ̂񂫂傤�A����΂�܂��B

(I look foward to seeing you it means a lot to me)
- �����̂��ƂĂ����̂��݂ɂ��Ă��܂��B This one is fine. Have you learned the respectful expressions yet though?
- ���ɂƂ��đ傫�ȃC�x���g�ł�. Why did you use the word �gevent�h just in the Japanese?
If you want to say �git means a lot to me�h �git is significant (if I can do a home stay in Japan),�h you could rephrase it to say �gI would be very happy if I could do home stay with you in Japan.�h Do you want to give it another try?

(I am only suggesting changes as I believe that the students should be writing sentences they themselves can understand and write.)
