Every shop should have good lighting, whether natural or artificial. My video work dictates limited natural light, so I was sure to have plenty of overhead T8 fixtures (6500k). You’ll hear me mention in the video that I was disappointed to see that the ends of the shop were just a little dark. Thankfully, I was able to get the contractor to come back in and drop in 4 more fixtures for me, two at either end. Now the light is bright, crisp, and evenly distributed from one side of the shop to the other.

While a single great product can’t usually support a whole business, it is beneficial to select one or two “headline” products that will form the cornerstone of your offering. This will often be an obvious choice: If you’re a coffee shop, your headline product will be coffee. If you’re a burger joint, you guessed it, it’ll be burgers. This product will often be the centerpiece of your marketing efforts and a way for you to “own” a space in a customer’s mind. For example, Jack’s Burgers makes the best cheeseburger in town and Daisy’s Threads has the most adorable scarves.

Ebates.com - Ebates is something I'll check after I've already found a deal that I'm going to bite on.  The rewards aren't usually good enough to compel me to purchase on their own.  But if you get an extra 3-5% cash back over your entire $250 budget, it can add up to an extra hand tool for doing nothing more than using their link to an online store.
At the very least get the basics of shop design right with great lighting, clean displays, and a well thought out layout. Once you have all of this pulled together you can add a dose of your own personality to the store's design to break through the noise and establish a connection with your target customers. The goal is to be memorable and maximize sales per square foot at the same time!
You can buy full solar kits that have all the components you’ll need except for the batteries and inverter. Kits come sized as small as 100 watts (one panel) and as large as 400 watts (four panels). Whatever you go with, we highly suggest getting an MPPT charge controller, which are a little more expensive but much more efficient than PWM charge controllers.
If I had it to do over again, I would stick to an entry level miter saw and table saw until I had both the funds and need to upgrade to more capable saws.  Because of this, I'd stick to the two saws we looked at in the $500 build: ​The Craftsman Table Saw for ~$150 and Hitachi 10 inch Miter Saw for ~110.  These two additions bring our running total to just over $500.  
We have a 5-gallon clear plastic Hedpak container that our sink drains straight down into. We really like this container because it’s clear, which means we can easily see how full it is. With 5 gallons of gray water capacity, we only need to empty it every 3-4 days. Dumping is easy - just remove the tank from under the sink and pour it out into an RV dump facility or other approved area.
