Funeral Planning

About a week and a half ago, we found out my dads cancer came back.  Then we found out yesterday that they are giving him, at most, six months, as it is now in the surrounding lymph nodes and his adrenal gland.  I have to plan everything funeral, services, and also including moving my wedding up because I NEED my dad there.  He is my best friend, supporter, and rock and I just want to make sure everything is taken of so I can enjoy the short time I have left with him.  He, unfortunately, has no life insurance or burial insurance, so anything will help.  If you can’t help, can you please share?  Thank you in advance.
