Hello Albert,
Welcome! You're definitely not the first one to look for suppliers for authentic Jordan's or Nike's, but the thing is these are not easily available through wholesale. Nike is very protective of their brand and to help protect their brand's reputation and to help combat piracy, they have limited the distribution of their shoes and other products to their own line of stores and a very select number of authorized distributors.
You might find this thread an interesting read.
Cheers!
