@clueless1117,
There are, I am sure, a lot of major computer or appliance type stores like Best Buy where you might be able to get some sales help (although I recognize that sometimes they're kinda useless) and maybe some financing although the terms are likely not to be too great.
You should also look on
Amazon as they do sell computers. I'm looking at your specs and I think they are for older computers; you don't necessarily need to get the absolutely newest-ever model. However, if you exceed the specs a bit, I think you'll find you've got a faster and far less frustrating bit of hardware.
I saw
this one on Amazon. It's $610.

This is just the hard drive and is not the mouse, keyboard, printer, cables or other peripherals.
Another option is eBay; make sure to only deal with highly-rated sellers where satisfaction is high - pay attention to how buyers have rated them. But that may be another source, and you might be able to get a refurbished bargain.
But keep in mind, older machines will get harder and harder to keep up as your company's software is updated, which it inevitably will be.
