How do I get a website or logo designed?
There are many companies out there that can help you create a logo or website. They make it very simple for you. You just document everything you want in details and they will provide you with quality results.
I tend to lean towards companies that crowdsource. Crowdsourcing is when your project gets worked on by an entire community of people and you choose the winner. In this format you get numerous versions of the work then you pick the winner vs only getting one version and not liking it. Crowdsourcing companies tend to produce higher quality results.
Some of my favorite companies are:
1) Topcoder Direct: http://www.topcoder.com/direct/
2) 99Designs : http://www.99designs.com
3) CrowdSpring : http://www.crowdspring.com/
Before you post your project review other projects. This will give you an idea of what you should be paying and also how and how detailed of a description.
