How to connect a portable usb type-c monitor via hdmi?

Question

Monitors

There is an old laptop, namely a 2010 MacBook Pro. It is quite enough for its tasks. There was a need to connect an external portable monitor. Such monitors, I look, only with usb type-c.
On a mini displayport laptop with sound, not thunderbolt (it has appeared since 2011). There is an adapter hdmi - mini displayport.

In these monitors, the power also works through Power Delivery, which means you need an adapter with additional power. Please help me find the correct adapter type.

Or maybe a monitor model with a large number of ports (hdmi, mini displayport), but not more than 20,000 rubles.
