What is the general pricing for a website with about 4-6 pages built by a web designer without a degree and about 2-3 years of experience?

Website pricing often has very little to do with the formal qualifications of the designer.  With regards to your designer in particular, 5 sites (assuming static 5 page sites) in 3 years doesn't really strike me as a significant body of work.  And anybody can learn how to use software.  It's what they're able to do with it (or more importantly, without it) that really matters. You can certainly find pricing in the sub $1,000 range for a simple static website, but people doing designs at that level are usually just starting out (and as such don't execute the project in a way that serves your needs best) or aren't doing significantly good enough work to warrant charging more.  You can also just as easily find pricing closer to the $3,000 price point (and beyond) and will hopefully be dealing with more experienced professionals who are more capable of truly solving your problem. You can then of course, with a bit more digging, climb your way all the way up to $10,000 or so adding perks like designer notoriety, innovative design, perfect code, marketing strategy, etc.  The monetary value of these perks are infinitely debatable, hence the higher price. This is assuming that we are talking about building a simple static website.  Custom development of non-standard features are always going to cost more.

Most website designers will charge about $500, give or take a few Benjamin Franklins for a static "brochure-ware" website consisting of 4-6 pages. The website design process should include competitive market research, keyword and meta information planning, content development and organization, website navigation and design layout, coding the first page, developing the rest of the pages, and implementing tracking and statistics. For my freelance web design business, a "brochure-ware" website usually  takes about 10 hours to develop. After the various steps, the client will have a well organized, easy to navigate, static website that supports the goals and purpose of having a website. At a rate of $50/hr (which is quite a bit below the industry average), that would equal $500. In addition to the cost of development, you will also need to consider recurring charges for domain name registration (usually about $10 per year) and website hosting (usually about $5 per month). If the designer does not have a degree, then it is important that they demonstrate a solid understanding of design principles, organization, and an understanding of the industry. If the designer has certifications in industry standard programs such as Adobe Photoshop, Dreamweaver, and Illustrator, that would lead me to believe that they are technically able to design and code what you are looking for. Another very important consideration is to look at examples of their work and see if it matches the style that you are looking for. In addition to reviewing examples of their work, consider hiring a web designer that lives in your area. That way, you can sit down and meet with them, find out if they are personable, and if they are able to provide good customer service. There are a lot of very good web designers that are great at design, but fail completely at providing outstanding customer service.

I'd recommend a different approach: value based pricing. See: http://amzn.to/dE3WNV and http://www.teehanlax.com/blog/2010/03/23/why-we-are-getting-rid-of-our-hourly-rate/ for background context.
