I now this is not a pleasant thought but ANY amount you for a logo is bargain.
Remember, unlike an ad, a website or a brochure a logo is AND SHOULD BE permanent mark ( unless your biz model or target audience changes). You also should take an active part in the design process, answering your BRAND DESIGNER's questions and providing info about your organization and your intend target demographic.
I want to create my own logo. How much I pay for a single logo ?
btw that phrase is self contradictory. are you creating your own OR hiring a professional?
