I only bottle condition and with the right process and ingredients (namely the yeast strain) I can get 'almost' zero sediment in my bottles.
If you use a yeast with good flocculation and sedimentation properties, and cold crash the finished beer before packaging, you should be transferring very little yeast to your bottles; just enough to carbonate the beer. So little in fact that you might find it takes a little longer to carbonate the beer properly but it will get there.
I brewed a Scottish 80 recently using Wyeast Scottish ale which compacts quite nicely. I poured a bottle yesterday into a pint glass. By the end of the pour the bottle was inverted and there was no beer left in the bottle. The beer in the glass was crystal clear and when I looked at the bottom of the bottle there was only a very thin film of yeast stuck to the bottom.
Sierra Nevada Pale ale is a good example of the same on a commercial level. If you inspect the bottom of their bottles it's literally the finest dusting of yeast, they only add enough at packing to ensure the beer carbonates in the bottle.
The short version, cold crash and use a reliably flocculent yeast that is known for compacting well in the bottle. If you do it right your wedding guests wont need be worry about pouring gently to avoid the sediment etc.
