Websites will generate leads on their own using SEO, which takes 3 to 6 months.Initially you need to drive traffic to your site using paid traffic such as Google Adwords and FB Paid ads. 

My personal favorites are near the traffic corridors, places like Summerville Place, off of Miles Jameson road, which is just off of Ladson road.

They can sometimes cost a few thousand, but the reports are substantive and go all the way from commercial comparables to traffic analysis.

It is always better, in my opinion, to set your rent slightly less than others to ensure you get as much traffic as possible. 

Other house is in mid-town, newly 'hot' area, so I see more opportunity for growth there...but I may be wrong...recession saw many houses here drop 50% or more, especially on the high end...Lastly, if you want to build be sure to check the SDC's for water, sewer, parks, traffic etc.

Oh... traffic is a non-issue!

If I was guess I would say minimum of 100k to buy the equipment .. then you have staff and that is always an issue.she also has an ATM  but that has caused her to get broken into a few times.. but it does create revenue.and its a lot of work.. she also serves light food  breakfast sandwiches  lunch  sandwiches etc. you need commercial coolers in the back to store the gallons upon gallons of milk etc.I have seen out our way these do pretty good and that's the little mini drive through stands that are manned by one person and or two max.. all in a little trailer with drive lanes on both sides.. hitting the commuter traffic. you get permission to put one in a shopping center parking lot that kind of thing.  

Just search on the web for Stessa and you should find it.

I am meeting with my web developer tomorrow and creating a content calendar that will be followed.
