Hey there, @abc11. Thanks for taking the time to reach out to the Shopify Community with your question. It's good to meet you!
We have a blog here that outlines more than 10 awesome product suppliers that you can consider using for your store. Some of them do have shipping facilities in the U.S, and even in the U.S and Europe! One such supplier is Spocket, for example!
There are many third party websites that also have information on suppliers that have warehouses in the U.S. I recommend taking some time to checkout some of the suppliers in the document I've linked here, as well as consult some third-party resources, to see if you can find a solid supplier to consider using!
