Hi Dear,
Good Day!
After reviewing your requirements, I will gladly help you to develop the platform like eBay or Amazon. I have already completed the similar projects before and very much clear in requirements, and ready to get started right away. Let me know when you would be available for discussion about project. I am also preparing a detailed proposal with all of my understanding that I will share in few hours.
Please give me complete details so I can share my development plan along with the wireframes. I am a senior full stack developer with 14 years experience also having a team of 90+ designers, developers, mobile developers, SEO engineers, Quality Assurance Engineers, Project Managers etc, who will work together as a team to convert your ideas into reality.
I am available 24/7, so you can contact me any time round the clock to discuss the project.
Regards,
SH
