Hi，

We are a tile wholesale business located in Anaheim, CA, 92805. We are interested in your products. We may use these for our samples. But we may also add these units to our inventory and sell to our vendors. However, I need more information about your products. Could you please provide: 

What is the unit cost if I add our brand on the units? 

How many tiles can hold each unit? the dimensions, the weight of each unit, and cost of door to door shipping for 20 or 50? or other shipping options? Also, could you let me know about your return, refund or replacement policies? Thank you. Our product sizes range between 12", 18", 24", 36" and 48". So, the display should be able to hold any of these.
