Any advice is much appreciated

[Joan Furbush]

Literally just started reading and listening to podcast 2 weeks ago.   I have nothing setup in terms of business cards, flyers, phone, etc..  I  was just  talking to someone that knew someone who was ready to put their house on the market.  I was called this evening by the sellers and they are  ready to sell.  My problem is I don't have a mentor and the one person I reached out to wants 50%.  Is that too much?   I really want to put a contract on the property.  I don't mind paying for anybody's time, I just   don't want to get  taken advantage of.  I just started and feeling my way through the dark, any help will be appreciated.
