The Perfect Web Developer

Web Designers are virtually found in every "street corner" these days, so finding the perfect web developer for your site can be a confusing and overwhelming task especially for the novice. For simplicity's sake, remember three things:

Know Exactly What You Need.
Understand What Is Being Offered.
Don't Be Afraid To Ask Questions.

Sadly, many web design/ development companies out there take advantage of the general public who aren't educated in the world of internet technology, charging obscene amounts for less-than-average sites with shoddy service, made with cheap templates or amateurish software like Microsoft FrontPage.

These charlatans also know little in the way of programming and getting your sites in the search engines, and a good way to spot a company like this would be to drill them on ranking, scripts and so on. If you aren't familiar with any of this, it would be a good idea to do so now so you know what to look for and expect.

Some questions you may want to ask:

How much they charge per page / per site.
What services are included with this?
Are there extra charges for updating, maintenance etc? How much?
The qualifications of the designers, programmers etc.
What about search-engine submissions? What can they do in terms of getting your site in the search-engines and improve your ranking?
How do they create their sites? Which software editors do they use?
Do they have a portfolio of clients and how can you see their work?

At the very least, a decent web developer should have the following:

Reasonable Rates

If you are just seeking a simple website, perhaps as a start to make your business presence known on the web, the prices should seem reasonable to you and should include some technical expertise, the use of decent graphics, animation and sound if needed, and other services like minimal maintenance and updating. Watch out for prices that seem too cheap or too expensive. A little research of the prices around could prove to be a great help.

Experience, Efficiency and Speed

Obviously, a web developer with experience can work with more efficiency saving you time and money. It wont hurt to check the company's credentials, portfolio, and past or current clients, emailing them if possible.

An Honest and Non-Pushy Attitude

Alarm bells should go off if the web developer you choose starts pushing fancy services or products which would obviously cost you more. A good web developer should be ever aware of your specific needs and budget, keeping a no-nonsense approach to finding the most cost effective solutions for your business. Of course, if "bells and whistles" is what you want, they should be able to provide that with relative ease.
