What do you mean by "we don't need to send money in advance"? Your reputation is at issue because you are a new account here, which is very clear. Why should people trust you with their money? You can just take money and run since you have no reputation to lose. How about using an escrow? At least then we can be sure that you will deliver the service.
Hold on, do not fall for this offer of not sending the money in advance. OP have posted the same thread in gambling section HELP WITH BETTING! BETTING FOR YOU! MAKE MONEY WITH ME! and have not got any good response. If anyone looking to get this offer, please first read the comments from the people on that other thread.
