There are just so many questions to answer it is overwhelming...have you really thought this through? Have you worked at an LFS? Do you know the ACTUAL time involved? Because it is a home tank X 1000. I worked my butt off at the LFS and there were about 6 of us. And the owner was there probably 7 days a week, good 10+ hours a day, too! Lots of algae, lots of water changes, lots of water testing, lots of things to feed...all the time.
How are you setting up tanks...individual systems or main systems? Will you Q your fish or put them in...what will you run specific gravity at...will you treat the tanks with copper or hypo as a general treatment with so many fish moving through...will you have coral systems...what else will you stock...do you intend to order from SWF and then resell (I'm not even sure they would really be up for that - you putting these fish into an LFS system may not be what they intended with their warranty...but maybe you plan on working out some deal)? If you don't order wholesale, it won't be economically reasonable to do it anyway, IMO.
There are so many questions, actually, I can't come up with a coherent way of putting them all together.
