WILL YOU ASSEMBLE THE MINIS FOR ME?

Yes. We actually prefer if you let us do the assembly. 

is assembly free? i heard it was free.

It is! Completely free.  

CAN I TELL YOU HOW I WANT THEM ASSEMBLED?

Yes. Along with these instructions, we will also need a complete army list. Please be aware that minis don't always come with the options needed to assemble them any way per their codex. For example, the space marine tactical box does not come with any lascannons, though SMs can field a lascannon as their heavy option in a tactical.
