you should have stopped at 25' and pumped that well. Like speedbump said you could have driven that screen too far and into some impermeable material
If your static water level is at 5' and you have to use a jet assembly to get that water out of the ground,you have to be getting alot of drawdown. That would tell me that either you are in a poor water bearing zone or your mesh size or gauze size is too fine. I would either bump that well back to 25' or try to develop what you have. There are two ways that you can develop that well without the use of a drill rig.
1) get a handpump,install pvc pipe open end w/no foot valve.tighten up the well head to the casing. Plug the holes in your well head and install the hand pump so its sitting on top verticaly inline with the drop pipe. Start pumping that well. At first you should be getting some pretty dirty water,hopefuly w/alot of fines. Once the water clears up remove one of the plugs on the well head to drop the prime. By dropping the prime that whole colum of water will drop down the well and send water in the reverse direction of the well screen. That action will break up any bridging that you created and will allow more fines back through the screen. W/ the foot valve in place you will not be able to do that. So repeat the process and if all goes well you should be able to make a well. This is the cheapest route.
2) go to your local rental spot and rent a mud sucker. get some fittings to hook it up and let it go. These pumps are awesome at developing wells. It will consistantly surge the well screen,breaking up the bridging around the screen.
Remember: "THE HIGHER THE POROSITY THE HIGHER THE VELOCITY" the more fines you pull out of that zone, and the faster the water comes through,the more water it will produce
There are alot of other ways to develop wells but these are the 2 that i advise for your application and limitations.
