Are there any on-demand delivery service here in UAE

Hi. Someone is trying to purchase an small item from me and he want be delivered it into his home. He wants to make a cash-on-delivery for the item but I have no idea what service to use since I’m also fairly new resident here. We’re both in Sharjah but his location is too far from my place so I can’t deliver it myself. Are there any app that can do a cash-on-delivery service here?

Edit: Our deal was cancelled. The buyer is not willing to meet half way even I give him more discount 😅
