Why don't you design your company logo yourself? The CompanyLogoDesigner makes it incredibly easy. You just have to click on what you like. No graphical talent needed.
And it's entirely without risk. You can try the software for free. And as long as you don't want to use the logo, you don't have to pay anything.
And what's more important, CompanyLogoDesigner costs only a fraction of what most design agencies demand.
