Raspberry Pi Python

Hello,

I would like to create a simple program for my Raspberry Pi 4, designed to be displayed on a 3.5-inch screen with a resolution of 320x480. This program should display the following information:

1. **Current date**
2. **Current time**
3. **Current gold price in euros** (this value should be updated in real-time)
4. **Total face value of the coins** (this value will be entered manually)
5. **Total weight of the gold coins** (this value will be entered manually)
6. **Intrinsic value**: This value corresponds to the value of the coins based on their weight in gold. For example, if the coins contain 5 g of gold, we multiply this weight by the current gold price.
7. **Investment**: € (this value will be entered manually and represents the purchase price of the coins)
8. **Profit or loss**: This value corresponds to the difference between the price paid for the coins and their intrinsic value based on their gold weight.

Additionally, I would like to:

- Add an image of my choice as a background.
- Play a sound when the gold price increases or decreases by a defined value, which I will set.

Could you provide an estimate of the cost for this project, considering the simplicity of my request?

Thank you.
