I have decided to start building a esk8. Here are my first of many questions,
What deck should I use for a cheap build? I am thinking either a longboard or a pintail.
What should I name it (pg names, nothing you wouldn’t say to a 10 year old)?
I am thinking maybe “Cheap-Skate”
Search will get you far.
But I’d start my deck search at skateshred.
Longboard is very generic, and pintail are longboards !
What you need to choose first is indeed the deck, but in relation with which enclosure is available with this deck
What is your total budget / intended use case? Different decks are good at different things 
What style of riding do you prefer? Do you like to carve a lot? Hit high speeds? Do you like dropped decks? What style of trucks do you want to use?
This is like half of the questions to consider when choosing a deck.
Total budget is around 600 ish. Use case is street riding and short errands/commutes.
I generally prefer cruising. Top speed? Maybe 25, but I will be going 18 ish most of the time. I am thinking caliber 2 trucks.
Caliber 2 trucks are prone to bending, and motor mounts slip on them because the metal is soft / not precise. Better to get some CNC trucks for esk8. Look into Boardnamics, he has cheap options which are amazing value for money.
Personally if I were you I would try to look for a deal on a deck + enclosure combo from someone, possibly used. That way your first build won’t be burdened by trying to find a matching yet strong enclosure for whatever other deck you find.
I will definitely check those out!
What is a good place to look for that?

I’ll give this stuff a look. I don’t think I need a super heavy duty enclosure because I am probably just going to have a vesc and 2 5ah 5s lipo’s.
I could just go with a good ol Tupperware for the encosure.
Honestly at that budget you might have to. And if it’s just 2 lipos and an ESC it’ll work well I think 
If you could try to budget 1/3rd for deck + enclosure, 1/3rd for drivetrain, 1/3rd for electronics + battery, that would probably be the best result.
My thoughts exactly. I could go with a maple deck of Amazon. Then maybe this would be the Amazon special build. Haha
Some good advice (which you might have already seen, but just in case):
