help! advice needed !

Hi knotties! So ive recently written on here for hair and makeup recs and I am finding that all the best ones inc those you’ve recommend are already booked for my wedding in oct – understandably! I found one whose pics I love and qioted price is ok but she already has 2 trials for my date booked so to secure my wedding date I would need to book now and have a trial later (paying a 50% deposit). I know a trial beforehand is ideal amd I had been always hoping to do that I guess I just left it too late to start looking. On top of of all this, I am currently going through a pretty serious health issue which means I wont be able to do the trial for about 2 months otherwise id try and book a trial with her asap ( im currently bed bound). All very stressful I just want to book now while a good one is left and worry about the trial later as I sort of havr to do the trial later anyway. But on the other hand it worries me a bit as I know how imp a trial is.  Would be really grateful of some advice or help worst case scenario I guess I could book, trial as soon as I physically can and look elsewhere if It turns out badly.  I know there’s heaps of options out there but I want to get a good one as I’ve had a bad exp with makeup for an event years ago.  Feeling very stressed out please help!! Sorry for the vent just feeling very useless at the moment.
