Congratulations to you and good luck and good health with the baby.
I had a friend in a similar situation, and I told him that he could do quite well by putting out the word to an upper-middle-class neighborhood that he was available to setup routers, home networks, etc. I suggested that he could start at a low enough wage that people would see the beneficial tradeoff to having him come over for a few hours versus doing it themselves.
After a few months, he hired someone to take the extra work he was receiving, and directed the more routine requests his employee. He had a full-time job plus all the extra work he wanted. Most people who hire him simply want someone they would trust in their home, and his service spread by word-of-mouth. He also got to meet many people who liked him and were impressed by his work ethic, resulting in many good connections if he ever wanted to pursue other employment.
My friend was an IT professional, the best support person at our tech-heavy firm, so he wasn't giving his time away. He did enjoy doing it, and he did enjoy the extra money. On an hourly basis, especially once he added the assistant, he was making more on the side than he did at his job. However, I believe he did start lower than that.
Good luck!
