Are you all squared away with temperature control? You'll need to do primary fermentation at ~50°F (approx 2 weeks), a diacetyl rest if you need/want to at ~60-65°F (~2 days), and lagering at ~33°F (usually 4-6 weeks depending on OG), while having the capability, for any temperature reductions, of stepping down temps by 5°F per day.
You could make a great Helles with the following:
97% German Pilsener Malt
3% Carapils Malt
Choice or a combination of German Noble Hops (Hallertauer, Tettnang, Hersbrucker, etc.) with ~20 IBUs added only for bittering (and maybe a smidgen for aroma at 1 min).
For a single infusion mash, mash in the low 150s°F for 60 min, about 2 qts water per pound grain. For decoction or step mash, use ~133°F, ~156°F, and mashout at 168°F. Boil for 90 minutes, adding bittering hops at 60.
With any lager, you'll need to dig deep for that patience you don't have!
