Uh, dude, I think there's been a language switch in here. Looks like we've got a non-English speaker trying to sell document services? Can someone please translate what this is about so we don't get scammed?
I gotta say, the title's a bit too enticing for spam. I'm guessing you're using a translation bot, but the "no prepayment" thing raises some red flags for me. Can you explain how you're planning to offer the cheapest rates without any upfront cost?
