How to order from a wholesaler

Hello all - this is a bit out of the vein of the usual posts here but I figure there are more than enough industry professionals here who could assist me…. I’m going to be running an event in Houston and the client is asking if I can assist with supplying wine and spirits to the event. Usually I work as a sub contractor of event planners or a brand (think luxury party favors), and the bottle of wine or liquor would be supplied to me in advance but this seems like an opportunity for me to expand my offering a bit. I also live outside of Texas. Is there any money to be made in me handling this for them? Any recommendations for a wholesaler in Houston I can work with?

Thank you!
