I need a website designed with a mobile optimized, fast loading landing page.

My firm needs reliable people who can deliver work on time.  People who can make good websites & landing pages like the below given website/page :-
https://swapnilized.blogspot.com/2020/03/what-or-how-or-where-is-god.html

The above website is a sample. More precise requirements shared as per the new projects

Pages need to be mobile optimized & load quickly. I need to get it connected to my social media platforms.

Hence the buttons for Facebook, Twitter, Instagram, Pinterest & Whatsapp also need to be displayed on the page.
If and when improvisations are needed, we will need revisions/improvisations between 3-6 months twice depending on the performance of the website. Only those who are open for 2 revisions/improvisations in the website after 6 months may contact.
