Same here lol 
This is understandable, I myself wanted to do this when I first started out back in 2018 with Crested Geckos before I ever even made a MM store. The Local Pickup thing didn’t last long 
Just keep in mind that with local pickup, you will have a whole lot less of a customer pool than if you did with shipping as an option. My reccomendation if you really want to do local stuff is to attend Expos if you have any local shows, my shows are a bare minimum 2+ hours away -not including if there’s heavy traffic in the absolute nightmare that is Houston- so be prepared for when you may need to travel longer distances with a bunch of animals.
Breed ONLY what you absolutely know you are comfortable housing and feeding long term (years in advance), and only what you have room for. Make breeding plans in advance for the next few years and stick to it- try to avoid changing plans too drastically either unless you absolutely need to. Do not keep holdbacks unless they will 100% serve a purpose in your breeding plans.
Be prepared for what you would need to do for a special needs animal that will need either to stay in your care indefinitely or go to a home that specializes in that specific animal’s needs
This is the unfortunate reality of being a small scale breeder in a world full of others… you will be lucky if you break even in costs your first few years. Though some years are much better than others its still difficult.
Be prepared to put everything you earn back into the animals. I’m 6 years into owning a MM store and I still put every dime of what I make from selling back into my animals, and even then I cut into my actual paychecks to cover the rest of the costs.
You will also need an animal emergency fund for vet visits and treatment costs for anything that can go wrong during the breeding process. I suggest you set the minimum to at least cover the worth of the animals you currently have… maybe more, some treatments are very expensive 
Be prepared and expectant of this, especially as a Local Seller. Sometimes sellers can go months without even a ghoster, and be mindful that you will be ghosted eventually… I had one from my first ever inquiry.
If and when you do decide to switch to shipping, be mindful of where your nearest shipping hub is. Be mindful of shipping material costs and labels. Be very mindful of weather conditions at dropoff, at the main Hubs (Memphis or Indianapolis) if going thru FedEx, and at pickup and package shipments accordingly.
Be aware of state laws in reguard to animal shipping and ownership.
Be prepared for the event of a shipment delay or DOA, these are things we hope to never happen but must always be prepared to have happen.
Hope that advice helps 
I’m going to go have a cup of coffee now lol
Edit:
I’d reccomend starting off with the lowest cost option, I forgot what its specifically called though… Just so you can get a feel for things for a little while and see if you do get anything out of it
