You can still guarantee problems in the future, so I suggest you find a reliable big company. As for the matters needing attention in decoration, first of all, you should give full consideration to the functions of each room in your home, including where you need sockets and where to put things in the future. Some things that look good but are not practical can be saved, and the style is best simple and generous. Don't make your home look like a business club. When decorating, we should consider the lighting and ventilation of the whole room. Carpenters just need to pack a window frame door or something, and use as little furniture as possible. There are many ready-made ones now. Some small parts generally need to be bought by yourself, such as door and window hinges, cable TV jacks, power sockets and so on. And attention should be paid to the transformation of electricity and water. The circuits are wired. It's safer to buy some pvc pipes in advance and wrap the wires inside. That's all I can think of. Good luck.
