dividends and how they fit into a long term plan

I am 60 years old and have a TSP account - I am looking at diversification and looking at companies that will pay a monthly dividend - the min ammount is 3K which I do not have.  Is there a way to dollar cost average (set $$ aside) until that min is met and then invest?



@Swhackett, Great question, I am forwarding your post to a subject matter expert that can help answer this. Thanks for reaching out ~Tom
