Hi, i saw your post that you need a web developer to develop your website.
It is a beginning but I am not a beginner at least when it comes to programming.
I am a Full-Stack developer with a Bachelor's Degree in Software Engineering.
I got 7+ years of experience in web development
******* Already have experience to integrate payment gateway API's ********
We have these options for hosting our APIs.
1) AWS web hosting (Expensive)
2)Shared Hosting
3)Virtual Private Servers
4)Microsoft Azure hosting(Less Expensive than Amazon)
According to me the Virtual Private Servers and Shared Hosting are good option for a startup. We can upgrade to Amazon later when there are more users.
Kindly contact me, so we can discuss it further
