This is my idea if you guys arent necessarily set on a church wedding:
Know anyone with a spacious backyard with a beautiful view? Have in the back yard, for free. Rent chairs. Another option is to rent a hall, maybe a clubhouse (use it as a wedding/reception venue), Set it up like a reception hall similar to this:

That way everything is in one place. People all already seated. Just Bring the food and the cake out after the wedding. A friend of mine rented a hall fro 750 and did this with it. Also for favors serving trays utensils, ballons, flowers, etc. go to http://www.dollartreedirect.com/ or http://www.orientaltrading.com/ui/shared...
For your invites-http://www.formal-invitations.com/ or Target http://www.target.com/gp/search/182-5500376-2029555?field-keywords=wedding+invitations&url=index%3Dtarget&ref=sr_bx_1_1- have kinkos print them for you after you make a template. Should run about 15.00 you can also so that with the programs.
For food- 2 options ask friends or family to cook- lasagne or spaghetti will give you more bang for your buck, a nice salad and french or garlic bread.
Or for a small wedding- catering might not be to expensive
Party punch- 1/2 gallon fruit punch, 1 pint raspberry sherbert, 1/2 liter lemon lime pop ( 7up Sprite or an off Brand) Also since there arent that many people catering for them might not be that expensive.
For a cake Costco or Sams club: They both make something similar to this, with out all of the frilly stuff at 12.00 a cake so about 36 and the stand is about 15. You can use some flowers to decorate it and cover the stand any way you want.

Another option is order a smaller cake for you 2 to cut, mount it on a nice stand

and serve from a larger sheet cake.
Don't be afraid to do the wedding bouquets yourself, theyre easy once you get a book from like hobby lobby and alot of the tools can be found at your local dollar store.
Do all of this and I swear you will come in at your goal amount or less. You just gotta be willing to put in a little leg work.
Dress...try Davidsbridal- buy a birdesmaid dress in white or ivory- youll save tons on money.
Also with makeing favors and bouquets- ask your mother and bridal party to come over and help make a girls night of it. Maybe cook a meal for them, nothing to fancy or order some pizza.
Ipod for a DJ...maybe rent some great speakers.
Forego the liquor all together except for a champagne toast
Centerpieces- hurricanes and pillar candels are always something cheaper. sprinkle petals around or you can get roses at costco and sams at about 15.00 for 2 dozen
