Dear responsible person,
First of all I want to thank you for the detailed project description. I managed to build the application in my mind and realized that it is a perfect match of my skills. The tools that I have been using for the past more than six years are one of the best possible for building desktop UI applications with Python. I have extensive experience in in Python and Qt. Qt is an advanced framework for building applications with UI. It provides all that is needed for this project - tables, drop boxes, advanced layout management (much better than in html). It inherently supports MVC pattern which provides us with efficient communication between the UI and the input data, the user and the output data. You can check my portfolio and see an destop UI application build with Python and Qt.
Regarding PEP 08 - it was a mandatory requirement through all this years. It is a part of my nature :).
Bellow you can see my rough estimation in terms of time. It has the same order like in your document:
1. Import records from a csv file in Python table: 2-3 days
2. Open a Form to show a few options...
building the app window, filling the layout and connecting all the data with the UI: 2-3 days
add search function: 2-3 days
add ability for user to edit the data: 2-3 days
3. export to csv: 1 day
extra days for unexpected situations: 2 day
So in the bid I put 15 days, but if you can't wait that long I can reschedule my time and finish the project quicker.
Cheers
