Grocery Delivery Business Idea- Shreveport

Why is there no Grocery Delivery service in Shreveport? Surely there are other people like myself here in town that have come to despise going to Walmart or Target. Surely those people also have disposable income ($10 per delivery to spare). It's a small price to pay for not having to get out in the 107 degree heat and fight the crowds for hot pockets and toilet paper (must buy in pairs).

I tried to do the math on making a successful go at starting a delivery business in my off-hours. I ran into a couple of problems.

1) I don't have enough energy. It may be that I don't sleep well at night or have sleep apnea... I'm not sure. Either way, when I get home from work I don't want to do a dern thing that resembles work.
2) See #1

The thing is, I think it could work here. It could work like this:

1) Create a website that listed a large selection of available items, with their prices and pictures. (Companies exist that will provide a database of food items with prices and pictures).
2) Allow users to register and purchase groceries at your prices (hopefully priced between walmart and brookshires prices). If the order is placed before 3PM, it will be delivered the next day. Add $10 for orders under $100, 10% above $100.
3) Have the website print a master list of groceries ordered by 3PM, combining all orders into one big list. Shop Sam's and Walmart, etc. for all items.
4) Bring groceries home, split into individual orders.
5) Refrigerate necessary groceries.
6) Deliver groceries the following day.

The main thing someone would want to do would be limit the delivery areas initially. I imagine that targeting an area like South Highlands (small, upper middle class area) would be a good way to fine tune the business.

If I were a college student with the ability to create this website, I'd be all over it... but I'm not. I have a full time job, bills to pay and little energy. It doesn't seem like it would take much... a website that can accept credit cards, a decent size car, grocery skills, a few ice chests, and a heavy heap of time and patience.
