Jim, former Corian distributor/kitchen dealer/top shop owner here...
All good advice regarding seaming, radius/routed cutouts, heat tape, etc. This is doable by a good woodworker, with some practice first.
Suggest you stop at a solid surface top shop, snoop around as a consumer, ask a lot of questions, observe some tops in the making, and buy some sink cutouts & scrap.
Take some time with the scraps, routing, cutting, seaming, edge buildup, etc., before you attempt the project. Make yourself some cutting boards of various shapes, sizes and edges in the process.
Also keep in mind that most distributors will sell sheet goods only to "certified solid surface fabricators", top shops, not so restrictive. Finished product warranty is normally only honored if installed by a certified fabricator, so your top will not be warranted by the mfgr.
You'll need good dust collection, a respirator, and fresh carbide bits...fwiw....
