I'm sorry but seeing your posts history, you do not seem to be a good candidate to manage campaigns. Most of your recent posts are vouch requests for assorted products and bumps in your own threads.
Furthermore, you have no reputation for managing something that involves large amounts of money, and even though you are applying for this job to gain more reputation, you still need a foundation before people can trust you anything.
Why would anyone trust you such responsability when they already have a lot of great options from reliable members such as Lauda, Lutpin, DarkStar, Yahoo, etc?
well what then shall i offer a currency exchange or lending service
Agreed on him, I too started without any background and I offer my services to people such as devs and I too don't have any trust but I try not to lack on constructive post since that's the only asset I can give. With good communication skills you can achieve that services.
By the way, you must offer atleast low amount on your start since those reputable members mentioned requires high amount since their professional on their job.
Yes, you can offer lending service without any reputation but you must need an trusted member to hold escrow for the collateral. On currency exchange service, I don't think you can offer that since it requires trust and reputation.
