Your wedding should be how you want it.

I would write a list -

What We Want

Celebrant - booked
Reception - possibly booked
dress
suits
flowers
cake
bombonerie
etc

and just say to yourself - today I am calling cake places, our budget is - ie $300. Go through the yellowpages and call 10 places, go and see the ones that sound good and book!

Cross things off your list one by one. There are some great wedding forums like belly belly out there, I would suggest googling "Australian Wedding Forums" and seeing what comes up. I was a member of a really great one buit can't post it here I don't think!

Good luck.
