Looking to buy used computers/ ( Laptops & Desktops )

I am looking to purchase 5-10 computers ( preferably Mac pro laptops ) per week depending on the demand of my store here in our area (u.s.a). I use to have a supplier here locally but they transferred to another state, if you are willing to do good business with me, I pay on time and order steadily. Only good business transactions please, I can provide good business to you if you can provide good products to me.

Thanks.
