I always find information on how to get more sales, or how to run a store, but I am not selling anything besides my service.
I need specific tips on how to advertise and expand a small business that offers a personal transportation service.

My company is small. We offer personal drivers for whatever need may arise. We offer point A to point B transportation, as well as long term transportation service.
My company is listed in search engines and I have Ad’s on my vehicles….

How else can I advertise? Cheap and effective? How to expand?

Also may i suggest retirement homes, adult communities and also area repair shops to pick up customers when they drop there car off and pick them up from work and back to the garage when vehicle is finished
