Paying For Wedding

The love of my life and I are planning on getting married in probably 2 years or so. My parents have already told me they are not helping with the $ situation. We are thinking of getting married in his parents back yard to save $. Does anyone have suggestions or are there any venders willing to donate items in exchange for advertisement. Please let me know either on here or at seainnandvalerie@yahoo.com. Thanks! Valerie =)
