I need vector files for 3 images

Information for the business: We sell tax services through a booking platform
Industry: Business
Design details: Looking to have vector files for the 3 below images that describe how we provide services.

I currently have 3 images but I would like to "improve" them so that they more closely align with the 3 steps taken to provide our services.

The 3 steps can be seen in the below link (TaxHack homepage). I would like changes to the below images to reflect "fresh" colors and be more fun for our young intended audience (20's-30's).

I need images for the 3 steps below.

First step: Discussions and data entry (defined as "Ask")

Second step: Provide strategic solutions (defined as "Hack")

Third step: Implementation (defined as "You Decide")

See below web site:
