If you're serious about learning how to do magic and with starting from the rock-bottom then you don't start out by casting spells, you start out by learning how and why magic works.
You see, there is no such thing as an "easy" spell or a "beginner" spell. One either understands how magic works and has mastered the basics...in which case the magic will work..or you haven't done that sort of work..and no spell will work no matter how "easy" it seems.
Casting a successful spell involves much more than finding some spell on the internet or in a book, saying some words, lighting a candle, waving a wand of any of that sort of thing. In order for magic to work you need to understand how and why it works in the first place. Grounding and centering, visualization, focus and intent, energy manipulation, etc are all necessary first steps to even begin to have a chance at a spell actually working...and more importantly to prevent a spell from back-firing on you.
So, my advice for anyone who is truly serious is to start by reading a few books and practicing the exercises those books will give you. Once you have mastered the basics you won't need anyone to give you spells, you'll be able to create your own spells that will be far more effective than anything you find on the net. Here's the books I suggest:
"Before You Cast a Spell" by Carl McColman
"Spells and How They Work" by Janet and Stewart Farrar
"The Veil's Edge" by Willow Polson
"Modern Magick" by Donald Michael Kraig
And the following links in this thread will also help you learn the basic skills necessary for effective spellwork.

If you are new to spell work, you might want to first learn how to make a ball of energy. You can find a lot "how to's" on this on this site. Once you learn how to make a ball of energy, and then fill it with specific energy (love, happiness, luck) etc, it will be easier for you to direct energy in your spells.
Another place to start is learning to cast a circle, which is making the sacred space in which you cast and do rituals. Casting a circle keeps the energy of your spellwork inside the circle where it can gather and get strong, while also keeping unwanted energy out.
You always may want to learn about the different tools used in witchcraft, different color meanings of candles, and types of crystals. Although you don't NEED any of these things. They can help your spell work be stronger and assist you in directing energy.
