Hello,
The provided short description has revealed only the general aspects of your requirements.
When providing estimations based on an example of a similar product, there is always some risk of misunderstanding, because the buyer and the developer see the same features from different points of view.
This is why we would like you to provide an exact list of functionality you need to have in your project, even if you have an example that is very close to what you are planning to achieve.
If any descriptions of the planned final product are already available – this would greatly contribute to our understanding of the project and would allow us to make an exact effort estimation.
Life-time Bug-free warranty is a part of our standard service.
Best Regards,
Andrei
