Hello,
Based on the given description, it seems that the front end part is done using html and the backend api needs to be developed. The final deployment would be on Google cloud, based on this understanding we have few queries which will help to understand it further.
1. The html/js responsive design is done, means the development of it front end is done, is it correct?
2. Do you want us to just integrate it with backend and deploy over Google Cloud?
3. For the development, we are assuming your Google Cloud account will be available like for staging purpose before it goes to production.
4. It seems from the requirement, the Google App Engine which is serverless Google Cloud service could be utilized with Standard Environment.
About us:
We are having more than 10 years of web development experience and have done multiple successful deployment over Google Cloud in past 2 years.
It would be good if we can get in touch for further discussion to get exact idea about the requirement.
** As the requirement has some queries, given estimates may subject to vary based on final requirement understanding.
Thank you!
