Need to buy some large formats for a wedding

We have a wedding coming up the weekend of June 3rd. I know its a long shot, but the grooms father would like to supply wine in large format, ideally 3L (double mags).

He is looking for a 30-35 price point based on 750 ml’s. Desired varieties (some flexibility here) and quantities:

Chianti/Rosso 7-8 D-mags
Chardonnay/Sauv Blanc/Easy drinking white 6 D-mags
Pinot 4 D-mags

Happy to source from multiple parties.

and this:, although not everyone will think this is easy drinking due to the acidity. A fine wine at a great price.
