To supawin, if you are really serious with running this signature campaign on your own, you should allow to escrow the funds.
We have a lot of escrow in the forum, I'm sure you can find one, we even have a campaign manager and escrow at the same time.
If you plan to hire a manager I recommend
Hhampuz or
yahoo62278 as they are the best in the business now.
Those stated are the reputed campaign managers of the forum. Hiring them truly benefits you, it ease you the task as well good community growth happens through these managers. Whatever might be the requirements they'll do it for you. There are more campaigns run by themselves, but in several cases it has gained bad reputation for the service promoted. In this way it should not affect your business profile.
