Vac-sealing will only slightly extend refrigerator storage.
I agree with the others if you are licensed check with local health authorities.
Vac-Sealing food will prevent off flavors from oxidation, but it won't impede food borne bacteria growth, simply because many of these will develop in the absence of oxygen (vac-seal). Many commercial vac-sealed items are heat processed after sealing, or even irradiated to prevent bacterial growth while in refrigerator storage.
If you are going for 10 days at a private event, I would immediately freeze them, then slowly thaw in the refrigerator a day or two before the event.
