Just Want To Be His

I am trying to plan a wedding for the 3rd of october, with very little money. We live in omaha nebraska but plan to marry in cresent iowa. Does anyone know approx. How much a jp would charge to come out and marry us??
I`m trying so hard to save up but just like some of you, everytime i get a little in the bank, another bill comes. We just had a beautiful baby boy on febuary 21st and i would love nothing more than to share the same last name as my son and the man i want to spend the rest of my life with.
