Hi, I think I am posting this in correct section. We need a marketing profession who can do marketing in facebook, twitter, digg and stumpleupon.
Please give more details. Marketing for what? Product, Service? Are you a new company, established? We have no idea if you're selling fish or if you're a charity trying to raise money.
Let me tell you one thing, anyone who has lots of followers in twitter, stumbleupon and digg can get you good results in marketing your products. The person should also have good amount of fan pages and likes or group members where your products can be easily promoted. Now you have to mention about your niche or your product, so the supplier can check if he/she has anything like this in your niche. You cannot just promote your product in any niche, this way you will never get the people you wanna target
