Keyword research

want simple keyword list / no website or url involved /
1] i will provide a keyword string [eg, a 2-word city-name] /
2] you will provide a long list of all of the relevant keywords /
a] this is for worldwide search results
3] for example, i have done a quick look at google-keyword-planner for a 2-word city-name and saw that there are almost 800 items in that list / i want the entire list / to be clear, i am interested in the entire 'tail', from most searched to least searched
we will begin with one such search, and then i will want a couple dozen more one by one, and then with several variations [ i put 'ongoing' because want to be able to have same person do several more of these kinds of searches]
results must be provided in an excel file / if the results are provided in a microsoft-access file, that would worth more to me
primary interest is in the organic search / cpc and paid is not the highest priority but it is of a bit of interest
