Be aware that there are plenty of pitfalls involved in ordering a machine from China. You might want to read about some other people's experiences with the process before sending large amounts of money off to the other side of the world.

Some people have reported good results, but there are also plenty of horror stories about machines arriving with broken or bad parts, incompatible electrics, shipping delays and unexpected charges, obsolete or pirated software, and total lack of support once the money's been paid. With the current pandemic affecting supply chains as it has, be prepared for even long wait times and lots more excuses for delays and problems.
Part of why you're noticing a difference between prices from vendors in your country and those overseas is because domestic companies usually budget for supporting their customers when their machines have issues. If, as you say, you're a novice at this, this promise of support is especially valuable to you. If your imported machine doesn't work, you're generally stuck either repairing it yourself or finding someone who works on Chinese machines, which can be difficult.
It sounds like you're planning on a lot of flat work, so a dedicated 4-axis machine probably wouldn't be the right choice; you'll want a 4th axis assembly you can mount on your machine or take off as needed.
