Good, Fast and Cheap

The best you can hope for is two out of three.
Take video production for example. Independent wedding and event video producers are all over the board with this one. Are the majority of them good? Probably, but that is subjective and from the perspective of the service provider, the client and/or her relatives and friends.
There are a lot of cheap video services providers out there. The technology is certainly affordable, providing a great starting point for newbies. Working out of home generates low overhead, start up costs...and that's good to a degree. Inexpensive is a relative term. It sounds a bit better than "cheap" still giving the impression that a video service provider who is "inexpensive" might be somewhat more credible than one who is cheap. To a certain extent, unfortunately, you do get what you pay for.
Fast. What's that? What's fast? One or two months? Less than one month? Two, three weeks? Ten days? The fewer days spent on editing a video product, depending on length, complexity and content, can result in omission of quality. A lot depends on what the service provider charges. What equipment, technology, creative resources does she have at her disposal? Today's tools can help be fast, and good, but it isn't likely your service provider will be cheap.
There are a few things you must do whatever your budget may be for video production.

• Set your budget, but make an effort to be flexible a few hundred dollars either way

• Make it a point to interview a minimum of five video production services providers

• Make every effort to obtain a minimum of two of them via references from people you know and trust

• Do preview samples of their work

• Do follow up on references: liked work, liked the people, performed as promised, any surprises good or bad

• Do establish how long (how many weddings or events actually produced) they've been in business

• All else being equal, what are your instincts telling you - run? Are you comfortable? Do you like them?

• Good instincts, a comfortable, agreeable feeling is one thing, but is she going to be there behind the camera

• You might have 12 months to get everything locked down, but give yourself more than a couple of months

• Wait til the last minute and availability (see above) diminishes, potential for making a bad call increases

• Whatever the promises - get it in writing. For your own protection you simply must get a definitive agreement

Follow the above suggestions and you might just be able to find a video services provider who is affordable (based on your flexible budget) - avoid "cheap"; fast - anything under four weeks can be considered so; and good - you saw their work, right? They've been in business for a few years, produced several similar events - right? The references were positive, you did contact them, right?
Keep in mind that while there certainly is an abundance of talented individuals out there who started producing yesterday, experience plays a major role in the positive outcome of a video production. People who have been in business for a few years, with a number of productions under their belts, tend to understand Murphy's Law that if anything can go wrong it will. They are prepared for equipment failure, with sufficient backup resources to get the job done, and get it done professionally.
You will pay for that experience but, more than talent, looks, production samples, production content, contract inclusions, or even personality, the premium for experience will be the single most significant portion of your investment in a professional video services provider.
