To go a lot lower than Black Cat would involve buying non-specialty beans, "office coffee," for a large drop in quality. Home roasting may be a better option, although the initial quality is not likely to be as good as Black Cat. With some learning on your part, it would improve. Green coffees of the quality found in Black cat can be had for around 5 to 10 dollars a pound, and cheaper in bulk (20 pounds or more). Since green keeps at least six months, and many for a year, you could buy in those amounts.
This will be a saving if you have the time to do the roasting and enjoy it. If time is tight and you find the job distasteful, there are no real savings there.
The cheapest roaster for the quantities you have in mind are the Behmor or a drum that fits a backyard BBQ. These will do OK for heavy bodied, low acid coffees. If you want something with more fruit, like the current Black Cat, you will need a device that roasts more quickly. The best inexpensive solution here is a combination of bread machine (its kneading paddle stirs the beans) with a heat gun mounted on top (to roast them).
There is more info on all these options in the home roast section here and on other home roasting sites.
