Creating a site from scratch and advancing to Australia

We had to create a self-writing site from scratch and further promote it.
The deadlines:
2 months for development
1 month for creating and implementing advertising
6 months to cover all costs associated with the development and advertising of the site

In the end:
We performed all the delays.
At the end of the month we conducted all the tests and optimization.
In six months, the profits covered all the expenses on the website development.
