Commissioning need help turning something into a 8x10 pattern

[zato]

i have the picture and i tried using the tool online but i'm stupid (100% true anyway) or it just hates me. normally i can get things to work no issue or find work around but not this time. i mapped it out in game and a 8 x 10 grid (8 tall 10 wide) is absolutely perfect hell i'd be ok with a 9x11 or something relatively in the same ballpark but for the life of me i can't get it to work. i can pay in TBT, NMT, or IGB i'll even do a design for you if thats what you want. i just desperately want this to work and look good. cuz i need me a basketball court.
i used paint tool sai and then turned it into a jpg the actual court lines i got from a google search (i can't draw circles well) so i take no credit for that but the coloring and distressing i did. then again i really don't care if it gets shared i just want my court and for others to know i didn't draw the actual court lines.

Spoiler: tada~

made some clarification. i specified 8 tall 10 wide to make it a bit easier? i'm asking too much aren't i? cuz the best i could do myself was a 8x15 but thats like 2 and a half extra characters that i don't really have room for right now.
