That's an awful lot of MG seeds to risk wasting buddy... What if your extraction doesn't go as planned and you're left with a weak or totally useless product? Wouldn't it be best to first start by doing extractions of small quantities of MG's so you don't use up your stash experimenting?
If you want to get into the LSA extraction game make sure to have the patience and dedication to read as much as you can on different extraction techniques before trying your luck at it. It's especially invaluable that you talk to folks who have been doing LSA extractions for months, years. You can find some of these LSA master chemists on Mycotopia.net.
As far as I've heard alcohol isn't that great of a way to extract LSA's from MG/HBR/Rivea. Actually, I've read of more people having success with water when it comes to LSA extractions than any solvent. Lab grade ether might work too, though I hear substituting lighter fluid doesn't work well at all.
If you're going to do a water extraction make sure to use mineral water as tap water can have toxins that harm the LSA's. Put your MG's in a tea bag and soak them in the water for an hour or 2 stirring frequently. Make sure this is done in a room that has as little heat and light and air blowing in it as possible because, remember kids, heat/light/air/moisture weaken LSA's. I've heard that doing a water soak for longer than an hour or 2 actually won't give you a stronger extract and may give you a weaker one.
Next just take out your tea bag and squeeze it lightly so as not to acidentally break it open and the water you're left with should be ripe with LSA's. I hear you can check whether your water has LSA's by pouring a little bit of your water into a cup that you sit next to a blacklight. If the water contains LSA's it's supposed to glow a certain color (I forget which) if it's near the blacklight. Just don't put your whole water extract near the blacklight since light and heat can harm LSA's.
Before you waste lots of time and effort doing LSA extractions i'd suggest you first simply try eating ground MG's. The good thing about eating them you know you're absorbing all the LSA's and not risking wasting some via an extraction. Just make sure your seeds are ground to as fine a powder as possible as the finer it is the better your body will absorb the LSA's. Have an empty stomach and mix the seed powder with some sort of thick, sweet beverage like a smoothie, malt, frosty, frozen capuccino, etc. Have patience waiting for the effects as they can take a full hours to fully manifest
