As your location is not US, you will need to do more work to get a good deal on a laptop.
I would recommend you start looking at local options available (Facebook marketplace),
Intel link,
Ryzen link - Location I put in Dhaka with 40 mile radius, you should change to your location and appropriate radius. Deal locally with cash and beware of scammers, if the price is too good, skip it.
Strongly advise you consider Ryzen5 4000+ platform. Ryzen delivers better iGPU performance, as well as better multicore encoding throughput. Added benefit of majority of ryzen laptops have user upgradeable memory.
For online shopping websites I am not too familiar with what options are available for you, I came across
Daraz and saw some options. Maybe there are others (Like in SE asia they have Lazada and shoppee, neither appear to ship to bangladesh that I can tell).
In closing, most advice from US sites and deals especially around US holiday season will not translate for you (especially with added customs). Focus on your own local direct sales (and consider used, that is were you will get most performance for dollar). Reconsider your base spec, do not overspend on a laptop, it will decrease in value the moment you purchase it, I would recommend aiming for 2/3 your current budget or less, stay away from junk, Ryzen 6 cores or higher, and intel 12th gen or newer (i3 is acceptable).
