Some people ask me to help booking their trips. They ask me because usually I found cheaper flights and hotels. So the question is not if exists any flight or hotel booking site as Kayak, Trivago or the service offered by travel agencies. The question is if there is any service that given a vague description of the travel you want, find the best options.
For example, if you ask for a trip "between March 2nd and 10th to a caribbean beach", they offer a touristic package to Cuba from 3rd to 10th, a flight to maldives islands in a 4* hotel, etc. The idea is that you just describe the trip you want and they give you some budget options.
I'd like to know if there is such page to redirect all my friends who ask me to do their holiday finding job :)
