Just typed something up and lost it. I'll try to remember what I came up with.
Photographer - If you have a college around, check with their art department for a student who's looking for work. Mom found someone locally who was trying to get into wedding photography. We made a deal with her - we paid her $200, plus paid for the film and developing, and we got the prints and negatives. Some of the relatives also brought cameras to the reception and sent us copies, and two uncles brought videocameras as well. Nothing fancy, but it worked.
Reception - If you need a location, check with local groups like Lions' Club, Kiwanis, VFW, etc. We rented the Lions' hall for the reception. $35 for the whole day, and they provided tables, chairs, and a kitchen with appliances.
We had a pretty low-key reception, I guess, but locally, sit-down meals with music and dancing aren't the norm. We had a buffet, with deli and veggie trays from Walmart, and some other food. No music or alcohol, which is pretty common in our area, and we didn't do favors. We got most of the decorations at one of the party stores (Party America, maybe) - tubs of mints, napkins, paper plates, tablecloths, etc. We had a few things to return afterwards, since we bought a few too many plates.
We got blank invitations online and printed them on our inkjet. No RSVPs for the reception, so we saved on postage there. We also splurged a bit (at my Mom's insistence) and got a few packs of napkins with our names & date printed on them. Got those online pretty cheap.
Luckily, my mother-in-law does wedding cakes as a side business, and did all the cakes for her kids' weddings. Look around for someone who does it as a sideline - Michaels here does cake decorating classes, so that might be a way to find someone.
For anyone else - I know the OP has a location already - look into slightly uncommon places. We got married at
Bridal Cave in MO - they have a package deal where they provide a photographer, the minister, flowers, etc. It was about equal distances between both our home areas, so we didn't have to deal with favoring one area or church over another. Plus, the Cave has limited space, so we had to limit the number of people we invited. I didn't have a traditional dress either, I found a very pretty white dress in the Coldwater Creek catalog, and even with rush shipping it cost less than $100.
Shop around at dollar stores, party stores, etc. I think we got our thank you cards at a party store, and we got blank cards that just said "Thank You" on the front, in a couple of designs. I see a lot of blank note cards at the dollar stores, usually 8 or 10 for $1. They're also a good place to look for decorations, nuts, mints, little bottles of bubbles, and that sort of thing.
