Providing tips to an old realtor has not produced results - entrepreneurship, is it the key?

Every generation needs a revolution - an entrepreneurial revolution

Somebody requested me to advise him, and so far it has been pro bono regarding the business we are engaged in.  And I said yes.

So far, he has indicated he has been negotiating for 4 sites all ready and has not progressed much.

      1.  1 untitled in his hometown.  7 hectares

      2.  1 titled adjacent to the to the site number 1 - titled 15 hectares

      3   1.titled  to the eastern side of the town, adjacent to next town 3 hectares

      4.   Untitled part of an estate, at the Eastern part of the province  7 hectare

While my timeline for the project is anytime this year and I am readying the operations, marketing, and financial plans, nothing from his end, ie producing the land has not prospered.  He keeps on changing his tack and probably he will not get anywhere.  

Since he has no Php I have emphasized on selling and negotiating skills and emphasizing long term benefits for the land owner, which we did as we built up our business long time ago.

What can be done to change his trajectory in business development?
