the bottom one with the laptop looks modern.
I think the first one is better. It's rememberable and looks trustworthy. The third one is overworked idea
The first one very close with what i want but none of that 3. Sorry.
30k is a big amount, i can't really get the 30k feeling in your design.
From my point of view, make it feel more grand. Gold colour with dark background should be better.
Nice try! Keep it up! :yeah:
