How to run a company remotly ?

[Huw]

Hi my father runs a garden machinery and ATV dealership that is a very lucrative company with a turnover of just under 1,000,000 a year. He is thinking of retiring this year and is looking for someone to take over, Now ive worked at my fathers garage all through my childhood and through my teens and know the ins and out of it. The only thing is i live away now over 200 miles away where ive bought a house and settled down with a partner but i still want to take over the company. My father is very old fashioned and still does everything with pen and paper so for me to tell him i will get a stock control system in place and everything working through a computer so i can keep track of it including CCTV cameras . I would be on top of everything and would be willing to go down at least for two days a week . how can i convince him i can do it and it would work? what stock control program should i go for? bar-code scanner i think is best to scan all parts to every job card ! please help !!
