The engine won't overheat in 2.5 minutes. If you're seeing bubbles in the reservoir, a head gasket is leaking. Stop leak won't fix that. Antifreeze in the oil will melt the first layer of the engine bearings so that will lead to more problems.
You might consider looking for a community college with an Automotive program. If engine repair fits with what they're currently teaching, and they're willing to look at it, cost will be very low but repairs can easily take a month or more.
