I am not going to encourage or dissaude you...  that is something you need to decide for yourself.  But you need to become educated about this world.  To start with read the "Newbie Manual" link in red at the top of this board.  Then read back on this board until you can answer every question without peeking.  Add to this, read the other boards to round out your education.  There is a considerable investment in time & thought but it is way too risky to do any less.  
Look for information on web sites...  there are free "template sites" that work just fine.  
You should have a free e-mail, not linked to your non-working world.
You should have a phone, not the same one you use personally.
You'll have to advertize...  read some reviews & you'll find links to ad sites.  Stay away from Craigs List as that is a favorite haunt for LE.  
You will need to learn screening techniques.
You should use the 2 call system.  

So this is what to look for as you learn.  Circumstances vary & you'll need to integrate all this into your business.  You'll need to be very disciplined to be self employed & self managed.  

This business is not for everyone.  Proceed carefully & thooughtfully.
Best Wishes,

Research research and more research! The more you educate yourself the better you will be able to screen, advertise, gain clients and get the most out of the business.  There are plenty of books and materials out there via internet to go through.  Good luck and play safe
