PBIViz Custom Visual modification

Hi All, I am looking for someone with Typescript experience to make minor modifications for a Power BI custom visual. The custom visual I want modified is called Play Axis. The source code is available on github [login to view URL] The visual loops through the data in my case it is dates and filters out the last date. I want to have different behaviour by making it select filters out range of dates staring from the earliest date up to the current date. Please quote if you can do the task within budget. Thanks
