some advise

hi,
i love the site and i hope everyone can help.
i run a sall cctv supply and fit company in the uk and after a chat with a good friend he was tell me about how many people are returning to the uk. He was say how much it cost to get someone to check his house and how expats house are targeted when they are empty.My question is when there be a service i could provide by fitting cctv into house from a single camera to full remote internet access.|I thought I would ask the people who are living the dream if i'm just wasting my time.
look forward to your replies.
