What kind of advertising worked best for you?

[FiddlerMD]

I am currently looking into advertising my video production company a bit and wanted to know what types of advertising worked best for others in my shoes. Particularly, what services get you the most return? what do people look for when they see "video services" advertised? One thing we DONT do is filming live events - so stuff like wedding videography is definitely out. we work with pre-scripted material only (you can see samples on our site)
Also, we don't have the budget for a TV commercial or the like .. so what kinds of outlets work well?
thanks
