You may be able to do a mechanical connection for your present tank using gaskets to seal the hole, as long as the area is smooth enough to keep the gaskets flat. If you put the hole in the true side of the tank you may need a valve to keep the fluids from coming out. Since you are burying it, you may even consider a whole new tank that would be bigger with an easy to open top lid for their suction hoses. You can pretty much think "septic tank" many of which have just a lid on top of a large tank in the ground. To pump it out they just open the top and stick the hose in (we have one for the house). You might be able to get creative with the tank you put in.

Close. Mine (which looks just like the pictured one) is HDPE (High-density Polyethylene).
I think I figured out what they were telling the OP to do.
Here are a bunch of toilet flanges. Let/s look at
this one for example.
The pipe size at the bottom either fits OUTSIDE 3" PVC pipe or INSIDE 4" pipe. What he wants you to do is mount it UPSIDE=DOWN, so the flange is flat on the surface of the tank and the pipe stick up, above the tank surface. This should be easy to do. Mark and cut the appropriate size circle on the surface. Drill a starting hole and use a
saber saw (portable jig saw) with a moderately
narrow blade, (the middle one in this group) to cut the circle. (Or use a hole saw if you can find one the right size.)
Place the flange on the surface and mark and drill four holes. It looks like 1/4" holes and 1/4-20 stainless machine screws, washers, and nuts will do it.
Get some gasket paper from the auto parts store and trace the fitting to cut a gasket. Or just use
this stuff, available at Amazon or your local auto parts store. You can't use too much.
Place a machine screw in the through the flange and hole. With one hand, apply a washer and nut onto the machine screw. With the other hand, tighten the screw. You may have to recruit a woman or kid with small hands for this purpose. When all four machine screws are tight, you are ready to finish the job.
For this step, get
this cleanout and
this coupling and some PVC cement. (If you are purist, you can get cement that has the primer in it, or get the cleaner/solvent separately.) Put some cement on both the flange pipe and one end of the coupling--they will bond almost instantly. Then put some cement on the other end of the coupling and the cleanout and they will also bond almost instantly, too.
You do not need much experience with plumbing to do this job.
