I am a Videographer. My wife shoots with a Nikon D50 28-105mm lens We use take these photo's and set them to music on a DVD. Problem is the this lens does not have enough zoom. Does anyone out their have any suggestions for a good zoom for this camera! We still need a wide angle but we want that Close up Too! Thanks  

Try Nikon's 18-200 Zoom with Vibration Reduction. They're around $700 which is pretty good for a lens that can serve most all purposes and has image stabalization built in. For around $300, you can buy a nice 18-135. It's quite sharp but no IS and not so far from what you already have.  
 
Now Sigma and Tamron both make fairly nice 18-200mm zooms at around half the price of the Nikon lens. They focus a little slower, don't have image stabalization, less optical quality, and don't have the build quality of the Nikkor, but if money is important and you use a tripod or good holding technique, the Sigma or Tamron offer the same zoom range at half the price.

I had a D50, but I've now moved to the D40X. in both cases, I used two lenses: the 18-55 that came with, and I bought a 55 - 200mm. the first was from kodak for £35 (~$70) but it broke fairly quickly. now I use a Nikon 55-200mm, bought for £150 (~$300). shop around for a good nikon, and you should be able to get it cheap. try digital depot

I also have the Nikon 18-200. It is a great lens. I use it the most as it is
a very capable and versatile lens. The 3.5-5.6 aperture is very capable unless
you are shooting in low-light situations.
