When you hire the services, you pay for the development of the page, and the only additional costs you will incur will be for the domain and hosting of the website (which can be paid either monthly or annually).
The timeline for each project varies based on the size and complexity of the website.On average, websites are typically fully developed in about 21 business days, although it may take less or more time depending on the client's cooperation and other implementation factors of the project.
There is no limit to the number of revisions. The project is only finalized when the client is 100% satisfied and happy with the final result, keeping in mind that changes are made while respecting the initial project briefing.
