A lot of vape shops will also build your atomizer for you (for a small fee). I bet if you go in knowing what coil(s) you want (wire guage, inner diameter, number of wraps/ohms) I'm sure they would be more than happy to oblige. Then all you have to worry about it wicking, which I'm also sure they would be willing to show you how to do. With nice thick wire coils and proper care they will last for months.
