tried so many DIY solution and i reckon its time i get professional help and resetup all my connection.
is there any Networking professional assistance i can get?

Either mesh or range extender, it depends on network usage.
It depends on how many users (or more likely devices) operating at the same time. Routers can say it can supports like 255 users at the same time but this is more theoretical.
I guess if you have no more than 6 devices, range extender would be suffice. However, mesh network is better choice as you fix the problem now and for future

The range extender also has another inherent issue. Since it is repeating the transmission, the overall network speed will be dropped by half since your data need to go through another hop.
There are things need to be observed also. Many mesh network said to be easy to setup since each mesh router connects to each other wirelessly. As you know, the further you are from the router, the slower your connection. SO, it is the same thing for the mesh router. How fast your mesh network also de[pends on how fast is the connection between mesh routers.
Depending on your house construction, a good router will probably sufficient enough. I bought an Asus router since that time I knew only Asus router can be be mixed/added later, regardless model, and configured as mesh network. The model I used is GT-AC5300 and put it next to my TV in the hall of my 2 storey house. I thought in future I would add more Asus for better coverage. However, I checked the data speed with my phone even at leaning to the farthest bedroom wall on 1st floor with closed door, the speed is still around 200Mbps.
The router is located near the wall in front of the house and the bedroom wall I mentioned is the wall at the back of the house. With that speed, I don't need to add another wireless AP
Another solution for your case would be connecting a LAN cable to another router on 1st floor. I would drill a hole and run the cable outside to the 1st floor to another router (depending where your BTU is located).
