This is a rabbit hole that has many turns. The 1x30 grinder idea is great to get started. Combat abrasive sell most of their styles in that size.
I would recommend 80crv2 as a steel to work with. It heat treats very easy and holds a pretty good edge. It's my go to mono steel. I quench it is peanut oil and have had few problems. Disclaimer is that if you read up on it there is a way to heat treat it to maximize its potential but a minimalist approach works. There are places that you can send blanks to get heat treated if you want to get something exotic.
Handle material is something that I did not spend a lot on early and did not know I was making some future problems. Try your hardest to find stabilized handle material. Especially if you are in BCS with high humidity. A soft wood handle will shrink if sent to a dryer climate. This could harm you handle and make it come off the knife. There are great guys out there that have all the exotic stuff. Terry Dunn in La Vernia has some of the best prices and selection around. You can find him on Instagram and Facebook and TNT enterprises. Or you can get into Stablizing your own stuff. Another rabbit hole.
As far as supply store around BCS I don't know of any. But jantz supply has just about anything you want. Also texas farrier supply in kennedale has everything as well. Bastrop has to the point sharpening. They carry a lot of the steel you would want as well as quench tanks and handle material. Also materialmakersupply on Instagram is on this board and has a lot of cool stuff for handles.
If you want to invest in great tools going with a 2x72 with a vfd is a game changer. But be ready to spend 2-4K depending on brands and features. There are cheaper out there but you get what you pay for. Or you can always build your own. I built my first one for around 500$. But it did not have a variable speed drive. I used pulleys and pillow block bearings.
If you want to forge you really would need to know all techniques above with added anvil, forge, hammer. There are budget way but it more expensive by the day. Railroad track works for smaller knives. Alec steel has a tutorial on a coffe can forge with map gas burners. And hammers and tongs can be sourced from the garage, Lowe's, or buys some handmade nice ones off line. My favorite one came from bounty forge on Facebook he is an aggie. Also get on the texas knife makers guild Facebook page. They post hammer ins and have a for sale page when people or liquidating their tools.
Sorry for the long post. You get me talking knife making, show pigs, or back country hunt and I lose my off switch.
Here is the grinder I built. And the new one I bought this summer
