I can see a huge market for weekend care in Florida where the majority are in service industry.
If you set a time limit on it for a financial goal, say 24 months, it may be worth it.
Night and weekends were typically 1.5 rate or more, so it adds up pretty quick. Unfortunately, so does the stress so long term won't be worth it to your family.
The biggest risk I see is strain on the marriage since carving out time for that seems to already be difficult. If your husband is on board with a time limit it can be a team goal.
