I know how you feel as I was the same when I started 3 years ago and looking for excuses to do cakes… I used to do for free for people’s offices as well… it took me around 18 months of doing this to build up a portfolio. The other idea is to use cake dummies… they are cheap to buy. I agree with Michal, your marketing idea is a great one… Good luck, I can see you are passionate about doing this wonderful craft :)
