. . . that I will never look for a Guru but I don't know if I would be able to search for one at the moment
You have to start from where you are. Not from where the guru you are unable to connect with and his senior manifests decide is required . . .
Some practices such as Chenrezig, Tara and quite few others are complete paths, dependent on your sincerity.
There are many transformative vajra or wisdom practices at the inner wheel or hub of dharma. We all start as a small cog in a big wheel of dharma
My question would be if there are actually people who practice Vajrayana without a teacher? And if that's even possible, at least some easy . . .
The question is one of feedback and advisement.
There are many who practice vajrayana and go on to Zen or Theravadin practice. It is not where you start. It is where you finish.
The Buddha did not start an esoteric tradition. However priestly witchcraft is always the final kaliyuga type power complex that requires a Maitreya (few hundred years to go yet) http://en.wikipedia.org/wiki/Maitreya
My teacher never minded whether I practiced Buddhism or not. How he taught would not even be regarded as teaching.
If you work from within your constraints, you may transcend your limitations. That is the plan.
I will put in a good word with the head of my lineage, which just happens to be you as a future Buddha.
