Summer Camp Education for my Children

My Children,  Zuri (Daughter) and Zion (Son) want to continue their education in the summer. They are very interested in the iD-Tech Summer Camp here in Philadelphia. The Camp starts in July but as days go by I see that seats are being reserved for many of the courses which means they won't be available the closer it gets to July. My son Zion is interested in the The "Build and Take Home Laptop" Course and my Daughter is interested in Coding.
My wife past away in summer of 2017 fighting Lupus for 6 years, so the past 2 years have been very challenging in all aspects of being a good, strong parent. It's a bit much for the courses and way above my budget but I wanted to try as best as I could to make them happy while getting educated on what they show interest in at the same time. I believe there is still a great opportunity to get the spots that are available since we are still in April.
The Entire family would truly appreciate any help that is offered for this cause. It'll definitely be a blessing if this could happen.
Thanks you all !!
Live in Bliss !!
