No bridesmaids. DH told me his friend's wife was disappointed that we didn't want her 9yo as a bridesmaid. Tough cheese.
Dmil was on her deathbed, so my sister led DH into the registry office. He asked her on the day and it really touched her (she had flown in from the antipodes as a surprise, neither of us knew she was coming! ). Could your Mil walk your future-DH in?
We had 50 at our wedding in total. No B-list for the evening.
No one did any readings. My Dad did a speech, my Mum did a speech and there was a surprise speech from DH's "characterful" Uncle. It was hilarious. DFil left after lunch (before speeches) to be with DMil (totally fine with us).
It was a totally stress-free wedding. Paperwork (i'm in forrin) was a giant pain in the culo but the rest was 123 easy as abc 
I think you need to sort out what is important to YOU, not 'how can i have a fairytale Kardashian wedding'. So, offer your Mil to walk dh down the aisle - if she declines, then that is it. You have offered a reading and a walking, if she wants neither then so be it.
Decide on bridesmaids who are good friends or close family, not because you need to make up the numbers or that two skinny ones balance out the fat one*
Don't tell anyone stuff then you won't havebto listen to others whinging or explain your choices. Eg cake - i don't like that bakery, cousin X's cake was from there and it was crap. Eg colour scheme - no one suits orange bridesmaids dresses. Eg music - how old fashioned/predictable/cliché. Ad infinitum.
Have one hen night, at home: dinner and pub.
If you have bridemaids, then pay for everything: dress, shoes, hair, makeup.
Don't make the groomsmen wear 3-piece suits, they look like idiots.
Provide a free bar - or at least free for the first hour/hour and a half or something.
