Customize Easy Hotel Plugin for WordPress

Hello, I hope you are well.

I'm looking for a freelancer to customize the Easy Hotel Plugin to add 3 identical features existing on the Motopress plugin.

The features that need to be added:
1- In the add rate form, we need to add a multi-select field for the days of the week:
- Lundi
- Mardi
- Mercredi
- Jeudi
- Vendredi
- Samedi
- Dimanche

The administrator can add a rate, for example, by selecting the days on which he wants to apply a particular rate. For example, between January 01 and March 01, you can select only the days :
- Monday, Tuesday and Wednesday with a rate of 15000 CFA
- Thursday and Friday 20000 CFA
- Saturday and Sunday 30000 CFA

2- For prices, it must be possible to set two different prices depending on the number of occupants in the room.
Presentation of the form (image complete form) :
- 1 person - Single price
- 2 persons - Price for two persons
- 3 Start date
- 4 Departure date
- 5 Multi-select field for days of the week
- 6 Room list

You can use ChatGPT to generate the code quickly and easily.
