Text him back and tell him when you are "paid in good funds" that can be verified by your bank you will ship the item.
What have you got to lose?
More than once I have needed parts that are not common nearby to me and are heavy/$$$ to ship from a distance, but have gladly paid the cost to get what I needed to get a project done.
Just recently I paid over $100 to get a $50 truck part sent across the country to me, seller did his part, and packed it well, and got it to the freight company and they did their part. Got the truck back on the road and my customer was HAPPY.
