Standard pier ready bottom rigs really don't need to be complicated at all. Use some cheap but tough 30# mono, cut off ~ 2', tie an overhand loop with 3-4 wraps big enough to clip with a snap swivel. Leave 4"-5" tag for the hook. Flip it over, do the same on that side but make your loop bigger so that you can loop it over your weight. Your choice as to whether to use snaps or snell the hooks. Some folks like to add beads above the hooks . I'm not sure it makes a difference.
Bet there will be a few folks who know a lot more about it than me who will likely give you better advice, but just for catching bottom fish that rig works and only takes a minute or 2 to tie.
I tie a swivel onto one end, 6" down i tie a surgeons knot with about a 3" loop. About a foot down I do the same, and then 8" or so after that Ill tie one more surgeons knot at the end with a 3" loop for attaching the weight. the 2 loops in the middle are for your hooks and you can add beads or floats if you desire. I use mostly 30 pound.
Learn and dropper loop. Absolutely no swivels or beads. That's my advice. While a snap swivel is nice addition that allows you to swap different rigs on the go...I prefer just using a double uni or similar knot to tie the rig on the main line. Minimal hardware will catch you more fish.
The standard two hook rigs you find in every bait shop are just a couple of heavy duty pieces of mono with a Perfection Loop tied in them. You can find directions for tying it here- http://www.netknots.com/fishing_knots/perfection-loop/ just make sure if you're using a ball bearing swivel you put that on the line before tying the knot and it should be located on loop B (from the link) before you push loop B through loop A. For me that was the hardest part of tying rigs was figuring out that loop. once that is done you can add whatever other hardware you want. To attach your sinker at the bottom the cheapest way would be to tie an overhand (or any other loop knot) in the end of your bottom section. When you attach your hooks you can put beads if you want, you can crimp hooks or swivels or you can tie on a hook or swivel. Personally I like to snell my hooks onto the rig so there is one less thing to break then tie the rig onto my main line.
