Selling my freelancing business and need help finding a buyer

I have a freelancing website that has made over $100k USD last year. The business offers services in virtual assistant, translation, transcribing, some web design and graphic design services. I am unable to continue to run the business due to personal reasons and, as such, do not have the time and am looking for assistance from an experienced freelancer in helping me find the right fit in a buyer for the business. It comes with 2 websites currently being updated and redesigned. 50% of the business came from freelancing platforms and 50% came from outside of freelancing platforms. Please indicate how you can help to find the right buyer. Am open to a percentage based upon sale price or a fixed fee upon sale. It's been successful and would really love to find the right fit to continue to grow the business and take it to new levels!
