Help me start up my grocery delivery business!

Currently, my little family of 4 (me, husband kids 3 & 6) are living with family as we try to put our lives back together. We are looking at being first time home buyers in the very near future but have little to no means to do so, including decent credit. Renting is out of the question because of our budget & needs. In general, the issue is saving & trying to repair our credit, all the while trying to pay child support, "rent" to our FAMILY and food & necessities for ourselves. I've built a business for a personal grocery shopper, meal planning, meal Prep & personal Chef services. It's what I do best, I'm only a mom! So, while this idea is great in theory to have additional income to lessen our burdens, it isn't easy nor is it free! I've researched myself crazy for grants and loans but can't seem to find many legit free grants, decent approved loans or kind supporters/reps. I truly am trying and could just use a little help! I need to provide for my family & help keep us afloat. Any and all donations or informational help is tremendously appreciated & would not go unnoticed
