As has already been stated, pilsners are just about the hardest style to do properly, especially if you are using extract for the base (extract is invariably darker than an equivalent all-grain recipe, due to the process it has undergone, with LME being darker than DME; LME also gets darker the longer it is stored, so if you do use it, get the freshest you can). Furthermore, if you are making the lighter sub-styles - the American pilsner, or American Light Lager derivatives - they often require adjuncts to get the light body. A European Pilsner, especially the authentic Czech style, doesn't have this issue, but it still is quite difficult to make properly. Pilsners are very sensitive to the quality of the ingredients, and to the brewing processes and handling. Making a good pilsner is a challenge to even experienced homebrewers.
One thing you absolutely need to make a pilsner is a fermentation chamber capable of holding lager temperatures (40°F/4°C) for at least a month. This is a relatively short lagering time, but still a necessity for all pils styles.
If you want something similar to a pilsner, but a lot easier to brew, you might consider a
cream ale. These were developed to be similar to pilsners, especially the American substyle, but are far less dependent on ingredients and temperature control (I once brewed one at temperatures up to 75°F with good results, though that was exceptionally lucky). They
do require adjuncts, which makes it tricky with an all-extract recipe, though using rice syrup and corn sugar should work nicely.
Here's a workable cream ale recipe using extract and specialty grains:
3 lbs. light DME
1.5 lbs. brewer's corn syrup
1.5 lb.s rice extract syrup
1 lb. cara-pils (steep for 20 min. in 150°F water and remove before boiling)
1 oz. Liberty hops (steep with the cara-pils)
White Labs Cream Ale Blend yeast
Getting the corn and rice syrup may prove difficult, however.
