From where you are planning to take off to Cochin!? Decent 3 to 4 star Hotels may cost you anywhere between 2000 to 4000 per day and a week long taxi you will get for between 15000 to 20000 assuming your mode of sightseeing would be taxi.
Hi. Very reasonable flight tickets are available for Cochin for the month of July and August
Also you get good hotel in all budgets in Kerala. So all inclusive a week trip for a couple should not cost more than 50-60 thousand
I've visited the places that u 've mentioned with my friends while I was in college. For us the ambiance of the place of accomodation (as that is where the most part of the expenditure goes) didn't mattered much, therefore it was around 6k per head for the trip, which included 2 days and 1 night on Kochi, 2 nights and 3 days in Munnar (in a decent forest resort, they are better than the hotel rooms) and finally 1 night and 2 days in Allepey.
Also if you want to reduce your travelling expenses, I suggest you hire a vehicle(if there is someone who drives well) depending upon the number of fellow travelers. We booked a Scorpio from Zoomcar, they have good packages. However, if you consider to choose in lavish hotels and even be a little extravagant in your travels, my estimate is that it will not be more than 15k for 4 nights and 5 days.

If you are thinking of backpacking, traveling in public transport, staying in hostels, then it won't cost you more than 20k as this is a place in India.
If you are planning on luxury travel then it may take upto 40k
