Long tail keyword research

I have started a new website and i am looking for keyword research to be done on the site.

The site is www.ryanseasyrecipes.com

I would like you to find 5 to 6 different categories for easy recipes and how to articles . eg Easy desert recipes ect

I want the categories to have at lest 5 sets of long tail keywords that can be used to write articles.

I want the categories to be highs search and low competition keywords with a search volume between 1,200 and 4000 searches

I want the articles to include relevant low, medium and high search volume keywords to help achieve traffic

Thank You
