Handling time 30 days? My products are Made To Order and need processing time

Hi there. I’m new to Amazon Handmade. I do carvings by order. I also have Etsy. In my Etsy shop all items are Made To Order and processing time is 4-6 weeks, depending of the previous orders. I don’t have many sales, approximately 10 sales monthly, but when customers order my product and want to wait 6 weeks, I know they honestly support and respect my works. How is that in Amazon? Are Amazon customers enough patient to wait for the project 6 weeks, or want it asap? Could I expect many sales on Amazon with this handling time?
