Brain/dad/grandads funeral

Dad set up a funeral plan to try & ensure that we didn't have any worries after he left us. Unfortunately he decided to leave sooner than any of us were ready for, he kept saying I'm not planning on checking out yet! Really just wish he could be back here right now to give me a hug. Anyway he still has a substantial balance outstanding on his plan & I've not got it all.  I want to give him the best send off I possibly can, he did everything for me & the kids while he was here. I hate doing this but I know he wouldn't like flowers or anything else so if anyone can spare a bit for his funeral costs it would very much be appreciated. Thank you to every one for your support.
