Hi there and welcome!
Living in Texas I can smoke anytime in the colder months provided it is not raining. It is a year around option for us.
The statistic I would like to point out is that I, and most I know, order 90% or more of their supplies online with the exception of items that are not cost effective for shipping (pellets, wood, charcoal, bulk seasoning, etc.).
Other statistics to consider if talking to lenders are how you plan to compete with online stores if you plan to be ONLY a brick and mortar store. We are in "Retailpocolypse" where brick and mortar stores are closing in droves and malls are being torn down all over.
I was reading an article that it is now reported that for every restaurant that is opened one is closing ALL BECAUSE the ones closing were not structured to handle food delivery as part of their business model and they did not want to adapt or failed to adapt. I mention this to call out other trends of current times that people are failing to pay attention to.
If you do not already have a legitimate numbers backed answer for how you thrive with and against the online market and for handling logistics in both shipping goods as well as receiving and managing/warehousing goods then I would encourage some heavy heavy investment of thought and planning into that area.
This includes product sizing and costs to help determine if you can plan to sale via an online retailer like
Amazon and make a profit or whether you try to go it on your own and utilize a sales platform like Shopify.
It's all possible, many well prepared and smart people make it happen every day so please understand that I am stating all of this in an encouraging tone.
I hope this info helps with areas of statistics to consider that go beyond the original ask :)
