Need to find a graphic artist/designer to help with artwork that will be printed on a large scale

I have artwork/custom design that I have 'made' for a 10' x 8' curved pop up fabric display (step and repeat) for a fundraising gala. It features the logos of the major sponsors. However, not everyone was able to supply white on transparent logo files that I could open on my PC (eps), so I had to modify a few myself using Canva. I am very happy with the final design, but am worried that my design will not size up properly and will be blurry. I have used mainly png and svg files. Some logos I had to convert to either png's or svg's. I think I did this correctly. I have the final design on a [login to view URL] and [login to view URL] that I will attach. Again, I feel like a fish out of water. I know what I wanted and needed to do, I'm just not confident that I succeeded. I'm not sure how to find out whether any logos will blur when enlarged. This really is my main concern. The printing company tells me that if I have a finished artwork file then all they need to do is print it. It would be great if someone could help me out. Apologies for waffling and I hope this made sense? Thank you.
