I'd be happy to solder things up for you and make it look nice. However, so much of crossover design is trial and error. You can get a perfect design in the tools and then have it sound bad because the woofer is a little high and the midrange a bit low, or the tweeter is a bit hot.
If you use a proven design, the odds of you getting it right are much better, however, variances in drivers could still make you unhappy with the final results.
And maybe I'm a glutton for punishment, but I actually like the trial and error part
