Apple iMac

I'm 18 and have just finished a 2 year media course in College, leaving with a level 3 diploma. I'm currently a freelance videographer/editor, but I want to persue it full-time and have a successful career in the industry. I have showcased my video editing skills vire my YouTube channel 'LUFC Lewis' throughout the last 4 years. YouTube was never something I looked at as a job, more a hobby, and a way to build my portfolio. I'm currently using an Acer laptop which cannot run Premiere Pro, it is becoming increasingly difficult for me to edit as I don't have the right equipment. I'm having to cut videos down just so they'll render, because the laptop can't handle larger files, which restricts me from producing a lot of the content I want to. Realistically if I want to start taking things seriously, I need an Apple iMac, which is built for running Premiere Pro. The YouTube video linked was edited using an iMac in college, it's an example of what I could do regularly with an iMac of my own. I know how good I am, but I know how much better I could be if I had this available to me. Unfortunately I'm not in a position to afford the iMac myself right now, so I thought I'd ask for a little help, though I don't take pleasure in doing so. If you'd be willing to help me out then feel free to chip in, just know you'd be making life a lot easier for me, and I'd be very grateful. I'd like to ask those of you who do help, to leave your full names so that I can thank you personally.

Thankyou
