I've raised £6500 to go toward cost of Edinburgh Fringe stand-up show 'David Ephgrave: Niche' (as funds are frozen due to David's dad passing away)

I was set to take a solo show to Edinburgh in August with my dad kindly putting forward the money for it, until my priorities were changed when his cancer worsened and I began overseeing his palliative care until he sadly passed away on 26th May.
I'm now officially still committed to the run - and already owe money / have paid some of the cost - but my dad's death has put his assets on hold, so I can't access the money he intended me to use for it.
I'm in a bit of a quandary: I'd like to still go ahead if I can as working helps me cope, plus it would be a fitting tribute to my dad who'd always supported my comedy. However, with everything that's happened recently, I want to resolve the situation in as quick, stress-free and non-psychologically damaging a way someone with longstanding chronic mental health problems - who's grieving for his dad - can do it.
The frustrating thing is the money's there - he'd offered to put it all up if necessary - but because he passed away, his accounts are frozen and I have to wait for probate to settle (which could take months) before I can access it.
(I also have to find the time to write and rehearse the show, which is hard enough with the amount of admin self-producing usually entails without theses extra issues.)
Taking part in the Edinburgh Fringe isn't cheap and my financial situation is tight (as a self-employed actor with a poor credit rating).
I put the rough total - including rent for digs, PR, a show tech, flyerers, artwork, travel, equipment shipment and the remaining percentage of venue hire due before the event - at £6500. I haven't included living costs, but I should be able to find the money to cover that.
If I could raise it here, it would eliminate some of the psychological pressure involved and enable me to do the show as a tribute to my dad without worrying about the finances, or potentially wasting the money we'd already spent.
All through my life, my dad was my unwavering support.
When I wanted to learn the guitar, he bought me one.
When I gigged, he'd carry my amp.
When I wanted to act, he paid for my training.
He seldom missed my comedy shows.
He was always in the audience.
He still is.
