The udhiya sacrifice is a confirmed Sunnah commemorating the sacrifice of Prophet Ibraheem (Alaihee Assalam). One sheep/goat or share in a cow/camel per family is highly recommended. Meat should be eaten by the family and also given to relatives, friends, and the poor. The act of piety is what reaches Allah (swt).
You can perform the udhiya by your own hands. As an alternative you can order the udhiya at the local halal stores; as well you can help your fellow Muslims around the world with your udhiya and there are charities that can help with this.International Relief Orgs for Udhiya:
Allaho-Akbar, Allaho-Akbar. La ila-ha ill-lal-lahu wa-Allahu-Akbar. Allaho-Akbar, Allaho-Akbar. Wa-lilahill hamd.
(Allah is great, Allah is great. There is no god but Allah. Allah is great, Allah is great. And all praises are for Allah).
The Prophet (PBUH) said, "There is no deed that is better in the sight of Allah or more greatly rewarded than a good deed done in the (first) ten days of Dhul Hijjah:". It was asked, "Not even Jihad for the sake of Allah?" The Prophet (PBUH) replied, "Not even Jihad for the sake of Allah, unless a man goes out himself for Jihad taking his wealth with him and does not come back with anything."
