3. If I had more money, I could do more for poor people. 
4. We would have had serious issues if they hadn't fixed that problem. 
5. What would you do if they fired you? (Not completely certain that's what you meant, you may want "What would you do if you quit your job?" instead)
6. I will do a long-distance learning course if it will give me qualifications that apply to my job. 
7. If we don't go on a holiday this year, I will do some more social projects. 
8. You would be a lot happier if you started helping people in need. 
9. If he had passed his driving test when he was 18, he would have been given a big party. 
10. Will they have a party if they buy that new hose?
