Is there any way to take a .jpg image of 50KB and allow one to print it very large, like 24" X 36" without it becoming pixellated? In other words, convert the 50KB image into a 5 MB image so the large print looks normal?

JPEGs, Bitmaps, PNGs and other pixel based formats will only pixelate when you blow them up, unless, of course, they are perfectly rendered rectangles (Remember, a square is a rectangle but a rectangle is not a square! ;) ) that are perfectly aligned with the edges of the "picture area". You can try taking them into a photo program and use smoothing, dithering, extrapolation and other tools within the program, but you will most likely be disappointed.

If what you are working with is Vector Graphics, you can scale them up and down without loss of quality.

Your best bet if you have a JPEG you want to use is to try to get it from before it was reduced in size or try to recreate it on a larger scale or higher initial DPI.

If you share your project, I might be able to help.

There is no way to increase the amount of information contained in a JPG unless of course you are on an earlier season of CSI and can read a license plate from across a dark parking lot with a 240TVL resolution camera.

If it is all just text, then maybe it will be easier to read but it will not be higher resolution. If you are trying to read almost readable text, try blowing it up only a small amount and move it around in front of your eyes and let your brain do the integration. There are probably some filters in Photoshop that will help restore some lost information but they can't really make stuff up, lost info is lost info.
