We need advice on technologies, timing, nuances of the development of a content web project

Good afternoon!

We are going to rewrite the old content project on a new engine and need advice on issues:
- What to take technology to the front and back in terms of development speed, development prospects, good SEO, complexity of support, deplo, etc. (so far without mobile apps)
- In what time it is realistic to implement the project (approximate TK is), the mode of work.
- What special is worth looking for (lone fullstack, front/back division, studio).
- In what format to organize the development, so that it went as dynamically as possible, with a minimum of risks of stalling the deadlines or, for example, getting a result that will be difficult to maintain.

You need to call a professional literally for an hour and a half.
If you are really a pro with 10 years of experience and have done a lot of cool projects, then for you it will not be an onerous paid conversation)
