Wanted House cleaning/maid service to remove cat allergens

I need to find a cleaning company that specializes in ridding an apartment of allergens, maybe even specializing in pet allergens. Or possibly recommendations for specialty cleaning products? (Cat dander is notoriously sticky and hard to deal with.)

My boyfriend is deathly allergic to cats (asthma, too) and he is moving in. I have found a foster home for my three cats, but my apartment must be ridiculously clean before he can live here. Every single bookcase needs to be pulled from the wall and cleaned, everything pulled out of the shelves, every inch and every item wiped clean.

I also need them to understand how crucial it is to get every inch and corner - not just nod, 'uh huh, sure' and give the standard quick wipe.

Thanks!
