My cats are partially raw fed and two have eaten some raw since they were tiny kittens. Their mother was a stray so I presume she was eating raw too!
I have never ordered anything from the company you mention but as I recall there was another regular contributor who did use and recommend them.
The raw that I feed is grocery store and meat market meat/bones/organs and some wild meats. My cats eat chicken, turkey, rabbit, goat, venison, beef. They have had a few other meats but won't eat lamb at all except kidney.
Feeding homemade raw and not grinding it presents the challenge of feeding enough bone that the cats can actually eat. They will eat chicken bones, some turkey bones, and rabbit bones (rabbit is very bony compared with other meats) but can't eat any others from those I listed.
When you order prepared raw meals or whole (small) prey there is no longer that issue. The issue instead is the expense! Those foods are usually many times more expensive than just going to the meat market and buying some chicken leg quarters on sale for 69c/lb or the occasional dressed rabbit for 3.99/lb.
But if you really want to order the kitten's food I would suggest first that you order a variety. The kitten should eat a variety of foods both for nutritional reasons and to prevent it developing specific food habits.
And even if you feel raw is by far the best I think you should definitely feed a few brands/varieties of premium canned foods too at least 2 or 3 meals per week. You would really be in a fix if some emergency happened where you had to board your cat or who knows what else and the kitty insists on fresh baby chicks, quail, or whatever.
A 10 week old kitten is going to be eating a humongous amount of food relative to its size. Even though a raw-fed adult might eat only 3 - 5 ounces of raw food a day (they require less canned than raw) I would suggest planning for 6 ounces a day. Then see how it goes.
Another suggestion is to NOT change the kitten's diet for the first week or so it is in its new home. Re-homing is tremendously stressful to a cat so I'd try to keep some things the same until it feels at home. Get a short-term supply of whatever the kitten has already been eating even if you disapprove of whatever it is.
