Economy parking at the airport would cost you $260 for 14 days and this seems to be the cheapest option around.
To confirm this, you could use this price checker, and enter the dates you are looking for.
Some hotels may let you park your car while you are working, as stated here

What about taking a rental car to Boston? Drive the car there, check in, and then return the car. When your done working pick up a car, and head home.
Rental cars are expensive now, but I would hope that 2 days worth of rentals wouldn't cost more than $560

That depends a bit how often you want to access the car. For example the Framingham Logan Express offers parking at $7/night. With bus fares that would be about $125 but it takes about an hour for inbound and outbound travel
Overnight parking is available at some of the MBTA lots (see http://www.mbta.com/riding_the_t/parking/default.asp?id=25204) and you could just take a train or subway from there, but that's probably not cheaper.
