First of all, for moderators or admin (Michel), you can move this post to the appropriate category as I don't know where should I submit it. But plz don't erase this post as I really need it.
Now for the post...
I know that my request here seems impossible, but who knows? So, I just post it anyway. Who knows there is an angel out there willing to help me.

I'll try to make this post as short and as clear as possible.
I've posted a review of my sales letter at:
http://www.copywritersboard.com/viewtopic.php?t=2892
It seems that not only I'm a novice in copywriting world, but also my English will be the main problem. So...
I'm looking for your help as
a copywriter to (completely) re-write my sales letter, however the compensation that I can give
right now is non-monetary compensation.
Perhaps:
- You are a starter copywriter who like to build your portfolio.
- Or you are just one of the God send angel to help others in need.

Bottom line, it's a kind of bartering. It's a barter between your copywriting skill and something that you want that I may have.
If you insist on monetary compensation... What I think as the best solution (for now & only from my side consideration) may be future payment after sales are generated.
- Of course I will give you a way to keep an eye at the sales number. I don't want you to feel insecure about it and I don't like to cheat people. Bad name is spreading faster than good name.
- Of course the payment can and should be large enough for you. $3,000 or more won't be a problem. I took the $3,000 from the price at copywritingcrew.com. If you want more, it's fine. I know my case is different.
- I'm not even dare to suggest a price, if you insist on pre-payment. The costs of living in Indonesia and US are very different. If you insist on the pre-payment method, the price will be a rip off for me and an insult for you. It's a lose-lose situation.
I don't mind if you just a starter or a pro. From my previous post above, starter copywriter is a lot better than non-copywriter isn't?
That's all I guess. If I write more, this post wil be very long.
Some people doesn't feel secure replying in open public. If you are one of them, just PM me.
Thanks for reading.
