Starting small business bought my first machine!

I worked for a boat canvassing company two years ago and I loved it and I’ve been waiting to find the right sewing machine and I came across a great deal on a Juki 1541S and I brought it home last week. I don’t have a ton of upholstery experience so I’m going to rip apart my Ford fusion and reupholster it to get the knack back for it lol. Any other big things that I need to take into consideration besides the complete obvious, any good tips or tricks on how to start advertising? Should I be going out and getting different walking feet or top stitching, etc.
