Help buy an ultrasound probe for Tanzania

Hi, my name is Dr Daniel Mclennan. I have been going to Tanzania for over 10 years to do charity missions for children with congenital heart disease. I will be heading back again in 4 weeks. Each time We go our sim is to educate and make the local team better so they can manage congenital heart disease independently. This year my aim is to teach them vascular ultrasound for access. To do this I need to purchase a butterfly ultrasound probe. The probe costs $2700. I would appreciate any help in order to purchase this piece of equipment.
