What engine to choose for the muzland.ru chord database?

Question

CMS

I lead an online direction in a popular guitar school. Now the task is to make a site with chords and videos like Muzland.ru or amdm.ru.
There will be about 5-10 thousand posts, we focus on 3-5 thousand visits per day, and in the future 10k+.
What is the best engine to do it?
I thought to do it on WP, because. it seems to be flexible and I know roughly how to adapt it to our purposes. But I'm afraid it will not withstand the load and then we are tormented with optimization.
We need to make it easy to find a developer who can tweak the engine to suit our goals. And that the engine can withstand the load normally.
The budget is still limited, this is only one direction of development, and in order for the employer to make a good investment, I first need to establish myself and my direction.
I understand that this rarely happens, but I want cheap and cheerful.
What do you advise?

Answer 1

any. honestly

Answer 2

Visits are nothing, it is important how much load one visit creates.
Habroeffect is just somewhere around 3-5k.
