However, the other advice you give are fairly good.
Since you are married and with children, would you recommend people in their 20-30 to avoid having children if the economical conditions are alike those in your country of Nigeria?
In Africa, once you are married you must have a child. It is also mandatory to get married. After a few years, if there are no children, you and your spouse's parents will start asking you if there is any problem. So generally Nigerians cherish marriage and children. Currently, people are not having so many children, just two or three is now the norm in urban areas. So I will never advise anybody not to get married rather they should get married. But you must plan before you get married and keep planning during the marriage. Marriage and children are beautiful things, most religions see them as blessings.
The economic situation of a country might also get better, as we are believing it will in Nigeria.
The economic situation of some nations can drive you nuts and as such, one has got to apply a lot of skills to be able to attain some sort of a comfortable lifestyle. You've got a pretty good one at OP, although there is one thing I don't really understand or perhaps would need certain clarification.
*Homeschooling: This is an unpopular option in Nigeria and as such, what are the government required criteria to home school your wards?
Meanwhile, as much as Homeschooling might seem like a good option to manage and fit in the economic situation in Nigeria, being the actual teacher to your kids or wards comes in a different environment and your wards might not give you the attention they ought to.
The Nigerian government has a policy of compulsory Universal Basic Education. This means every child must go to school and learn basic educational knowledge through both formal and non-formal education. But you must take note of the following:
Qualified teachers: The teachers in a homeschool must have the basic certification from the Teachers Registration Council of Nigeria.
Examination: Your children must also write internal and standardized tests. My son will be sitting for the Nigerian Federal School examination by August.
Curriculum: Your homeschool must have and follow the scheme of work and guidelines of the Nigerian curriculum. You can also adopt other countries' curricula in addition to the Nigerian type. You must not also teach what is against the Nigerian Policy in Education.
Learning Environment: You must ensure that you have the space and time to teach your children. There should be chairs, tables, shelves, ventilation, lighting, etc. Your children should at least be comfortable.
Quality Learning and teaching materials: You must have the scheme of work of all the subjects and buy these textbooks and ensure you cover them.
Time maximization: One of the benefits of homeschooling is that you can plan the classes to suit your schedule. Classes can hold at any time even at night or early hours of the morning. Sometimes during holidays, we fixed classes. In homeschooling, you must maximize every single time you have because you cannot predict tomorrow.
Rules and Order: Our home school have rules which are executed by the prefects and teachers. We have property prefects that arrange and safely keep school facilities. The library prefects are in charge of books and sanitary prefects clean the class.
In a typical Nigerian school, there is order. Members from Nigeria can confirm this fact especially private schools. They use both the carrot and stick. My children know and treated me like a teacher during learning because I behave and act like a teacher. My wife is the disciplinarian and as the headmaster, I handle higher disciplinary situations. After school, they know us as very loving parents and we are best friends. It's just for you to make them understand that we have two important institutions in the house: the home and the school.
