Japanese Translation Needed
 

Can you translate the following into Japanese?

Hello, xxx

A friend of mine gave me your xxx doujinshi and I really liked it.
I'd love to buy more of your doujinshi, but I can't travel to Japan.
Is it possible to order them directly from you?

Best regards, xxx

Why don't you give it a try, and then we can help you with your mistakes. It's unlikely people will want to help translate a complete letter without you putting in any effort.

I'm actually really bad at Japanese, I didn't even understand all of the doujinshi.
(I also seem to lack self-confidence.)
If you could help me, please do.

Not unless you try. This is a teaching moment.

Can you correct it?

Did you use Babelfish or something? Almost none of your sentences have verbs! I'm wondering how you enjoyed a doujinshi without being able to read it.

I changed some things significantly (including word choices) because I think you went about things wrongly:
Get rid of all the わたしs and あなたs. Japanese people almost never use the former, and you should use the person's name instead of the latter.

Also, I'll admit I floundered a bit with the level of formality because I'm not sure what you're going for. I also kept things simple and didn't polish it up because I dont have time; it's thrown together quickly, so take it with a grain of salt and trust someone else over me. I'd never write a letter in such a style.

But like I said, I made it quickly: I'm going on a road trip starting today!

Thank you very much for your help.
