We understand that you need a website for your educational institute which is based in Mumbai. We are a recently founded IT firm and both of us partners stay in Mumbai only (Borivali). On top of that, a vast majority of each of our formal education (schooling, junior college, etc.) has happened in Mumbai (ending just 2 years ago) so we have recent first-hand experience of being educated in Mumbai.
Both of us are skilled in website designing and development, not only because of holding bachelors' degree in engineering but also because of having on-the-job experience of the same. However, we would like to mention that the quoted rate and timeline are purely for an extremely basic website containing only static webpages. We wish to inform you that there is great variety in the type of websites that can be made for educational institutes and this will accordingly affect the cost and the time period for completion. E.g. one can have an extremely basic website (as mentioned above) giving your institute's background, courses offered, staff member profiles, institute address and fee structure. On the other hand, one can even have an interactive website wherein students, faculty, alumni can interact with each other (using e-mail as well as social network), share course materials for online learning and prospective students would even be able to subscribe to news updates/admission announcements for your institute.
Hence, please let us know further details about your exact requirement
