Procurement live Phytoplankton

[airvicconcre]

Hello. I don’t live in the United States however I am visiting end of month. Staying in Denver for 3 nights Sunday through Wednesday. I would like to purchase some live Phyto especially Rhodomonas Salina however all online vendors ship Monday through Wednesday annd I’ve spoken to a few of them and they cannot guarantee delivery on a Tuesday even if I order on a Sunday. Are/Is there anyone from whom I can buy this strain of Phytoplankton in the Denver area? Any help would be appreciated. I will visit Aquatic Art during my stay in Denver but I do not know if they sell live strains of Phytoplankton.
Thank you
