Pine shavings are bad for animals, even rodents. Switch to aspen. You can even use newspaper or paper towel as well.
For beginner... either a small locale of boa from the northern part of Central America such as Honduras, Mexico, or Nicaragua, or a Spotted Python. They get to be around the same length as a Corn Snake, but the only different is the body mass. A Spotted Python has more mass than a Corn Snake, have similar requirement in temperature, humidity and enclosure size, and they are not as flighty while handling. Boa husbandry is pretty easy as well, they have a slightly higher temperature requirement of 75-92F, with 55-60% humidity.
I currently keep my fully-grown 5' boa, which he is big for a male considering most males of the Nicaraguan locale only get to be 4', in an underbed storage bin to give you an idea.
Which one is my favourite? My Nicaraguan boa, apart from a 9' Columbian female, is my favourite out of all the ones I handled in the past.
Basically snake husbandry is pretty easy, a water bowl, an enclosure with a tight fitting lid, a heating pad and two hides. By the way, most captive snakes eat mice.
My setups?
Heating Pad - $15
Tubs - $3 (for those shoeboxes) -$20 (for those underbed storage), depending on the size
Water Bowl - $1 (Dollar Store)
Newspaper - Free
Kitty litter bins (as hides for full-grown boas) - $5 each
Plastic saucers (as hides for hatchlings) - $0.25 each
