I do have my own personal beginning in the spritual quest, but I prefer not to give my personal experience as an example. But I will still give you some tips:
1. Try to invoke the mercy of Krishna and His Devotees, by this definately a concrete path will be created for you.
2. Never fear to venture alone in your quest, with time certainly you'll start getting the required support. But at any point in time, you are never alone, the Lord is always seated in your Heart, knowing your endeavours.
3. It's not you who decide, how'll you'll know the Lord, it's He who'll take the responsibility of everything, provided that your quest is sincere.
4. Not being attached with any Sampradaya is Good, but definately you'll get your Knowledge from atleast one of them, there is no way out. Be more concerned with what the Guru laid and not too much with what His followers are doing. All the Sampradaya teaching Bhakti to Vishnu is Bonafide, but in the beginning you'll need the eye to discrimate for the right ones and don't worry that also will be made available by Krishna.
5. If there is something more, I'll tell you.
