The AW 2000 mah can handle a maximum of 10 amps discharge. This means that the lowest you can build on it is a 0.42 ohm coil.
Any 18650 battery will work with that mod, 18650 is a designation of size, 18 mm wide by 650 mm tall. The only caveat is that button tops add a little bit of length.
Ok dual, quad, micro...
It actually doesnt matter at all how many coils you put into a device, what matters is what the final resistance of the build is.
Lets say you have 8 coils that are exactly the same. You put one of those coils in an RDA and measure the resistance, lets say it measures 2.0 ohms. If you now do a dual coil set up with those coils, your final resistance will be halved, so 1.0 ohms. If you did a quad coil with those coils your resistance would be quartered, so a final resistance of 0.5 ohms. If you could somehow get 8 coils into the device the resistance would be 1/8th of the single coil, so 0.25 ohms.
As long as you maintain a total resistance that is higher than 0.42 ohms, you will be fine, regardless of the number of coils you have.
A micro coil is something alltogether different, and is a name that I absolutely hate. When people refer to micro coils they are usually really talking about contact coils. Again, it really doesnt matter what the coil looks like, as long as the total resistance is above what your device can handle.
Heck, I could build a coil in the shape of a bunny, and as long as it is higher than the resistance my battery can handle, no problem. Of course, wicking a bunny shaped coil may be difficult, which would result in a whole host of other problems.
Regarding budgetvapor, they have decent shipping, they use USPS with either priority or first class shipping, so it very much depends on where you are located. I have recieved packages from them within 3 business days.
