We currently have a website solution project in which I am involved. We are also outsourcing the development from local software-development companies. We have not selected a vendor because we are at the request for proposal stage.
In the project plan, I need to allocate a timeline for the development of the website solution (which involves more than just a website). How do I go about allocating date/time for this? Best case I need the website to be finished in a month; however, if I put that in the project plan, then it would not be realistic.
I have the website requirements and I thought about placing estimated development times for each requirement however there are too many line items to enter times for.
