And here's a link for capacitors *LINK*

You need a start capacitor rather than a run capacitor at a guess. I rarely see run capacitors (most I've seen were in HVAC use) but most machinery motors use start capacitors. In the link page the run caps are at the top, so scroll down a bit to find the start caps.
The capacitor should be labeled with a range of values in microFarads, usually abbreviated either MFD or uFD. Just match the range as best you can. Biggest problem I've encountered with replacing capacitors is one time the formed housing on the motor was too small for the replacement capacitor, but that is unusual.
At work we're only a 2.5 hour drive from El Paso, so if we order from McMaster and the product is coming from their El Paso warehouse we get it the following afternoon if the order goes in before 11 am. I believe they have a warehouse in Denver too, so you're about halfway between the two and should get the cap pretty quick.
The only thing about changing capacitors is to always avoid shorting the terminals. With a faulty one the odds of getting a shock from stored charge is minimal, but it is just a very good safety practice to make into habit. Treat all capacitors as charged capacitors and you'll never have a problem.
