Need a logo for a website and for business cards etc

I require a professional looking logo made for my company. I want my company to have a nice fresh and appealing look, therefore the logo needs to convey this. My company does deals and offers discounts from other companies and is similar to such other companies as cudo, spreets, dailydeals etc but has a modified concept. The logo should somewhat portray the saving of money. Here are some logos i quite like: [login to view URL] I love the style of the wolf. [login to view URL] I love that its simple, modern and to the point. [login to view URL] Very modern, I like it. Perhaps a man with money in his pocket.. or something to do with money.. or a global view with australia showing on the globe (black would be nice) like this [login to view URL] I don’t know, be creative! I want to see 5 different logos that vary of which i can choose from, use your imagination! Proof must be shown that you’ve done similar work before i’m looking for elegance, and yet on the edge of design. I'll leave the positioning of the text 'Pledgesaver' up to you.
