Not sure what part of Virginia you live in, but Richmond to Miami is roughly 950 miles. I used Richmond to Miami with the example dates Oct. 1st - Oct 22nd on Priceline.com for the flight, cheapest flight (round trip): $260 Delta Airlines. Using the same search terms for hotels near South Beach: Avalon Hotel - $172/night (2.5 star) Princess Ann Hotel - $62/night (2 star) With the Delta flight ($260) + Princess Ann stay at $62/night x 21 nights ($1302) = $1562 for hotel and flight.

there are quite a few sites that you can search that will likely give you the best prices available. check out the website BookMe and you will be able to compare prices on all the reputable travel sites in just a couple minutes. it's very convenient and will save you a bunch of time and money. Also, make sure you buy them online... otherwise they charge much higher fees for phone orders. good luck.
