Affordable travel agency in Dushanbe?

Hi lovely people! 🙏

I'm hoping to visit Tajikistan towards the ends of this month for my birthday.

Planning a 4 day trip and during one of these days I want to visit the Iskanderkul lake and Lenin's bust at Istaravshan.

Can anyone recommend a good reliable travel agency who could do a one-day tour?

I'm a female solo traveller and will my be on my own.
