Where I buy ROM10 Cards or ROM3 CARDS in big quantity?

If anybody knows where I have to go to buy ROM10 or ROM3 cards about 3Kpcs per week, please let me know because I had a inquiry from Canada for Dish network.
Please also let me know the answer about the questions if somebody knows;

Q 1. ROM 3 or 10 card is Funcard in Europe?
Q 2. What is chipset which is used at smart card of ROM 10 or ROM3 card?

Thank you so much in advance for your help.
