Is it more practical to rent a commercial space or hire a sales representative?

I am a new mom and I have a small online business. My inventory is all over my house and with an 11 mo. old baby, my house becomes almost unliveable. I have been thinking of renting a small commercial space to get my inventory organized and attract more customers. After crunching numbers, I will end up spending $20 to $25K to get my store up and running. My monthly overhead will be $2,225 to 2,600/mo if I run the store my self. Another option is to rent a public storage and hire a person to sell my products to suppliers and other retail stores. This way, I can have more quality time with my baby. If I do this, my monthly overhead will be around $3,900 to 4,200/mo but I don't have to shell out $20K to $25K to start. Which of the two options do you think will give me more revenue and will be more beneficial to my family?
