Write a series of different sentences for different keywords

We have a series of keywords and for each we must write multiple sentences. The keywords are property related. For example we have the keywords CCTV so some sentences could be

We were impressed with the security with it's CCTV
The property was very well secured with CCTV
CCTV makes this a well secured property
Security is very important to us so it was good to see CCTV

Using our software we will choose one at random and display it as a review on our website. These sentences must sound like we ( the website owners ) have written the review.

We have over 70 keywords from which to form these sentences.
