Where do you work? I mean where does your household income come from?
How would you like it if I came to your job and did it "just for fun", so that your boss fired you because he or she no longer needed you?
That's basically what you are doing to your local professional photographers who charge a fair fee for their skills and services in order to feed their family and keep a roof over their heads.
Sorry if this sounds a bit harsh or blunt. But it is the sort of reaction you should expect from some people, when you make a statement like that.
But, as to your original question, I honestly cannot think of a much worse lens either for wedding photography or senior portraits! If I'd hired you as a second shooter or to shoot my wedding and you showed up with that lens on your camera, I'd send you home. But then, that's one of the differences between being an amateur and being a professional... the professional will have the right gear for the job, as well as the knowledge why and how to use it.
A wedding is a once-in-a-lifetime event (presumably!) A photographer shooting one should have minimum of two cameras, two flashes (built-in flash won't do), a modest selection of lenses, spare batteries and plenty of memory cards. Anyone who doesn't have those really has no business shooting a wedding.
The "most budget" lens kit I'd consider using for a wedding would be a 50mm f1.8 ($215) and 85mm f1.8 ($475), along with a wide angle such as a Sigma 10-20mm ($275). This gives you two of the most useful portrait focal lengths (also ideal for senior portraiture), as well as a wide angle for reception shots, broader shots of the church, etc. Close-up shots also can be important (rings, cake, bouquet, centerpieces, etc.)... but can be accomplished inexpensively simply by adding macro extension rings to either the 50mm or 85mm lens (macro ring sets from Opteka, Zeikos or Kenko cost $75 to $125).
