I recently got a 2000 savage ls650 (my 1st bike). I was wondering if anyone could recommend some large to very large saddlebags that are easy to install. I would be using them to make deliveries for the restaurant I work for if that makes any difference.

food delivery..Hummm...pizzas? steak and spuds? etc..etc..
must(should) be horizontal...
large back rack.....
saddle bags not deep(from fender out) enuff for most food containers....san sakO mickey Ds

If you recently got your first bike and are not a very experienced rider, I would not advise that you make ANY deliveries for work. In fact, if you were my employee, I would not allow it at all.

Motorcycling is dangerous enough without having to worry about meeting delivery timelines, negotiating through traffic while not fully concentrating on riding, and being in potentially unfamiliar neighborhoods. There is no way as an employer that I would pick up the kind of liability you are asking for.

This isn't Korea or Vietnam, and there are other, safer options. Save your bike for getting to work and for riding for pleasure. Not for being a motorcycle courier - at least until you have MUCH more experience.
