Hello,
I propose writing the app within 5 days for your stated budget of 4000 INR. Ideally you will be able to test the app within three days, with the final days kept side for adjustments and to fix bugs. The visuals will follow standard Android designs (e.g. CardViews). Each list entry will show a product name and picture, and the remaining details will be shown in full screen when the card is tapped. A search box will be added to filter down the list of products as the user desires.
I will need sample data or a description of the format of the product data (you mentioned a document) in order to build the app. Payment will be expected once you are satisfied with the work done.
Please feel free to contact me if you wish to discuss this further.
Best regards,
Chamath Ellawala
