How Much Does it Cost? 💸 😬

As noted by @LuchoTurtle in https://github.com/dwyl/image-classifier/issues/97#issuecomment-2038195115 💬
This "hobby" app is costing us _considerably_ more money than we originally expected. 📈
The most recent invoice on Fly.io was **`$48.61`** for **Mar 1 - Apr 1, 2024** https://fly.io/dashboard/dwyl-img-class/billing


The _current_ month (April 2024) Amount Due is _already_ **`$14.34`** and we're only on the **4^th**!!

If we extrapolate the total will be **`7.5 x ($14.34 - $5) + $5 = $75`** 💸 🔥

This is already more than we spend on our Internet & Phone bill ... 🤯
If the cost could be kept to $10/month it would be fine. 👌

# Todo

+ [x] @LuchoTurtle please have a think about what can be done to reduce or cap the cost. ✂️

I'm keen to keep this app available for people to test _without_ having to run it on `localhost`. 💻
But if the _casual_ visitor is costing us this kind of cash, _imagine_ if this got to the top of [**`HN`**](#23)! 😬
