About how much would a wedding like this cost?

My boyfriend of 3½ years proposed to me on Christmas morning. :) I’m a big planner, so I’m already thinking about the details. We want the wedding to be on August 17, but we aren’t sure when we’ll be able to afford it. We’d love to get married on August 17, 2012, but we have no clue if we’ll be able to pay for a wedding that soon. I don’t want to be one of those people that is engaged for 4 years. Might as well just be dating if you ask me.

So, our guest list comes out to be about 75 people. We live in Lexington, SC and are planning to have the wedding here or in Columbia. Aside from the honeymoon (which is a whole other issue), we’re wondering how much our wedding will cost.

I would really like to be married in a church, but we don’t attend church. Being in the “Bible belt”, I’m not sure if churches here will allow us to marry there if we don’t attend. Does anyone have experience with this?

We plan on going to a local bakery for our cake and family members are going to cook a buffet style reception dinner. My dress will cost about $700 at David’s Bridal and he’s going to rent his tux. Our groomsmen and bridesmaids are going to pay for their own attire.

I just don’t know what this will cost us. One of my family members had a nice small wedding for $10,000. Is that what ours will probably cost, once you take everything into consideration?

I’m just kind of lost on the whole thing. I don’t even know where to start.
