wedding reception wine

[Hethyra]

I am planning a wedding reception for 70 or so people, I want to serve 2 glasses of wine and one glass of champagne to each. I also want a less expensive variety. (Better than 2 buck Chuck but under $9 ) What is a good inexpensive brand of merlot? What white wine should I offer? (nothing too sweet like Geurwurtzaminer) We are have salmon, lemon herb chicken and a vegetarian entree. How many bottles of wine and how many bottles of champagne should I buy for 70?
