After an extensive research, I found a good YouTube Clone script, which I needed for building my website. It was great that they have set a live demo of the script on the site. I did a thorough testing of the script, and found it to be closest to my requirements. It was named as StreamTube YouTube clone script.
They contacted me within 2 hours after I submitted a contact us form. I was given a reasonable quotation for developing my website and two mobile apps for Android and iOS. As the script had almost everything I needed, I just asked them to customize the look and feel of the front-end and hide some features that I did not want. Overall, it was a smooth experience working with the people here at StreamHash.
It has been three weeks since my project was completed, they still reply to my queries. Good customer support. Keep the good work up.
