Ready.....set.....goooooooooooo!

All, I'm currently looking for my first deal. I have a few questions. If I look through Realtor.com and find a house like this one for example...$72,000 3 Bed, 2 Bath 1,296 Sq. Ft. 0.21 Acres and find this info from Zillow.com ZESTIMATE™: $89,565 Value Range: $80,609 - $102,104. Is it common practice to contact the seller of this property or would this be considered unethical since there is already a realty company trying to sell this house. Would this property even be one you would consider (I haven't seen it yet I was just browsing realtor.com). I want to do this right without stepping on any toes. I've been contemplating contacting a realtor and forming a team, he finds me properties and I give him a percentage (other details will be worked out). Is this recommended?

Thank you, and any recommendation a greatly appreciated.
