As nucacidhunter mentioned, I would highly recommend you work with the VGP group. I've work with the VGP and had excellent results for my de novo projects. They even do the hybrid assemblies!
If your budget is tight, I would add HiC data from Phase Genomics or Arima Genomics. If phasing information is important, then add some 10X Genomics data (
