Hi Sokunthea,
Coding is not a magic. some unforeseen issues may come during development. So, we can't predict the future. But by considering the, task in the proposed game, whole communication will now, our experience & developer skill set, it’ll take around 4 months to complete the overall project, from the starting date of the project. We need to consider 10 days of unavailability of resources during the progress of the game due to the festivals holidays in the October. But we will try our best to finish the work before the estimated months.
But during development we also expect your quick response & regular feedbacks to keep project on track. As mentioned in project proposal document - "We are assuring you that we will finish the project in given hours, until and unless you change the requirement or add some new things in the project. If you don't do that then we'll definitely finish the work in given time only.
There are NO HIDDEN COSTS with the hourly base job. What we quote is what you pay. If the scope changes during the project then a new quote will be agreed before proceeding with any changes (It's called UAT)."
Here is a link to our DETAILED PROPOSAL :- [login to view URL]
FYI : we are planning to put 2 developer on this project.
We look forward to working with you.
Best regards,
