I was in the same spot you are a few months ago.
Friends liked my photos and asked for photoshoots.
I refused them all and did some with closest friends and family for free to learn more how it is to shoot more seriously.
I bought my first DSLR 3 years ago, I did my first paid photoshoot 2 months ago
First get to know the camera (I also use the D5300).
Learn to focus, learn to expose, learn to compose.
Learn about shutter speed, aperture, ISO, DOF, etc.
There are so many things to learn - It's really a complicated "world".
I've studied Photoshop at University but it wasn't enough - had to study again to learn some more things (love Phlearn tutorials).
After that I begun to study Lightroom, and it's an amazing post production tool also.
I use both now and I am still learning
Did 3 photoshoots so far, I have no contracts yet, not even a defined price, but I am getting there...
Customers were pleased with their photos, but sometimes things can go wrong.
I decided that I would do "packages":
For example:
10 printed 4x6 (10x15 cm) - 40$ (At switzerland we use CHF, not dollars, but it's almost the same so I will say $)
20 4x6 - 60$
30 4x6 - 80$
A 8x11 (21x29.7 A4) is 20$ each until 5 prints - after that it's 10$ (5 "8x11" are 100$ - 10 are 100$ + (5x10) = 150$).
I charge also 2$ for each full res photo, edited and converted to JPEG.
My "best sell package" (only did 3 photoshoots

) is:
10 printed "4x6" + 1 printed "8x11" + 20 full res photo on a flash drive - (50 cents for kilometer if I take my car and 25$ for the service).
So - 40$ + 20$ + 40$ + 25$ - 125$
With no time and photo limit.
After that I show the clients all the photos, they pick their favorites, I print and send them...
I ask them if I can use some photos to my portfolio.
But I have to work on some contracts.
The 25$ for the service are paid in advance, so even if I have to refund the client, that money is mine.
But, as I've said, I'm no pro.
I am at the very begining and have so much to learn.
Here are some photos
Mother Daughter session 1
Mother Daughter session 2
Godmother and goddaughter session (this one wasn't paid, but since I can't post from the other paid photoshoot, i'll show these)
Sorry for the long post, but I felt in need to share my experience with you, because I'm also new to this "world" (not to photography itself, but to be paid to do it

).
And sorry for my English - I'm a portuguese dude living in the french side of switzerland
Cheers
