Mom would you work 50hrs per week for $2000 each paycheck ?

I have an opportunity to start working on Saturdays from home. If I start working on Saturdays that will bring me to working 50hrs a week. With overtime pay I would be making a little over $2000 a week. Problem I’m a mother of small children and would feel guilty about working so much. My husband and I are doing ok financially but we’re in need of a bigger house. My plan is to only work the increased hours for 6 months to a year. My husband is on board and agreed to completely take over childcare on Saturdays while I’m working.
