In addition, take a look at some of your favorite songwriters' material and study their lyrics to see how they put them together, their choice of words/imagery/etc.Another cool lyric writing trick I sometimes use when I'm stuck that I learned from Diane Warren (one of the all time most successful songwriters) is to find an existing song you like.

It's good that your figuring out material costs, but don't forget labor cost, unless your doing everything yourself.

Problem is for new people looking to go into it, the majority of the material thats out there, ie comes up via search engine costs money.

Do you call or send some kind of marketing material via mail or email?

I have not read any of his materials, so I won't pass judgment on that.

Generally not, but that depends on the nature of the lien, like a Lowe's credit card for materials.

Keep track of your materials cost, and in the future request contractors to provide line item quotes with materials separate from labor.

Finding contractors and materials today to complete in six months is hard for first time buyer. 

I'd absorb material from youtube on sales & market and particularly real estate related marketing.

I”ve had a chance to read some books , watch podcasts and review the material here on bigger pockets.
