Dear client. I have just read your project description very carefully. I have rich experience of 8+ years in Ruby on Rails website development. Also, I have ever been built a large website by using React JS, Vue.js, Laravel, CodeIgniter, and PHP. In my opinion, your website is a very larger site. So, the first milestone is $1500, the second milestone is $1500, the third milestone is $1000, the fourth milestone is $1000. I think so. Feel free to let me know if you hire me. Thank you. If you hire me, I will be my best for your project to complete. Also, I can work in your time zone 24/7.
