When I am done with the game can I submit it to be paid or should I wait till the judging of the games I over to make it paid

There won't be official judging, but people will play all the games -- if it is paid, people won't likely play it unless very interested, so I'd just add a price later at least after the weekend after the jam.  Most anyone playing jam games will be done after next Sunday.

Up to you, but would be great to get your game played for sure.
