Im cheap!!!! and need wedding advice?

i just got recently engaged and everybody keeps asking me well when's the big day? i want to answer them but i have no money for a wedding. or atleast a fancy one. i just want frriends and family. and have a fun reception. no banquet hall of fancy napkins. i don't care about that stuff. anyway does the church charge anything. and how much are decorations? i have no idea what to do and everyone is gonna have me do everything myself. so can somone tell me what they did for thier wedding to make it fun cheap and simple ?
