Hi ashleybrooks! Welcome aboard!
To start, I am going to tell you that I am answering with my 'gut' feelings. They are in NO WAY intended to offend or upset you. My comments are just what popped into my head when I read your post (and the replies).
I was once told that good chefs don't make good restaurant owners. I understand you're not opening a restaurant.. but your 'food supply' business is about as close as it could be.
Now, I don't have a problem with the weekly total. After all, there are a bunch of diet commercials that state 'food costs are extra' or some other 'pricing'... but I think buyers are smart enough to figure it out. If in doubt... simply add it. If it's $25.00 a week, add something like 'that's just $5.00 a day'. YOU do the math so there's no confusion.
Where I really have a problem is this. The costs. You can't control the costs. Food costs change. What about delivery?? What happens when nobody is there when you deliver?? Ok.. you go back. Who pays?
I am not sure what $$ profit you have in a $5.00 meal, but if the meal is more than just two or three crackers... there isn't much 'margin of error'. I really, honestly, do not think it's worth the attempt. I am sorry.
I am saying that because you're only one person. Help? That costs! Car? Gas? Promotion? That costs! If you're dealing with food, it BETTER BE FULL COLOR PRINTING. Oh yeah... that costs.
Now... having shot it down... why not consider this. I will cost you far less than your idea. It will mean only a few hours of work a week. Your downside risk will not be much at all, and your chance for success.... well, that's killer.
One of the most profitable niches online is diet and weight loss. Why not target part of that market with the diet handbook/ cookbook. In fact, it may very well grow into the food delivery business you're talking about... but at least I am confident that you could make the online business profitable within a year.
You MUST develop a list. You create cookbooks and other content that you can sell. If you work this right... you develop a bunch of smaller products that eventually 'spin' into a huge, all in one... gotta have diet and good eating manual and home study that sells for... uh.. maybe $200? maybe $300.?? Maybe more?!?
All of this takes time. It is very, very possible. You will have to get a website and proper SEO (Search Optimization) but it is possible. You may even start local by hosting diet cooking lessons... that's just another slant on the business.
I think you will have a much, much, much better chance at being a success that way... as opposed to trying to be a glorified pizza delivery person.
I hope this helps. If I can help you more... don't be afraid to PM me.
