Similiar site like rally.io or fyooz.io

I need a similar site like rally.io or fyooz.io except users cannot create their own tokens. Our company will create and release the tokens. Our clients have had their own cryptocurrency social tokens created. We need a platform to list them on for their followers to purchase so they can buy products our clients sell. Our clients will be selling NFTs, retail apparel like shirts, sweaters, and hats that are created by the clients. We would like a page where all members can exchange any client token for TRX. Please save yourself time by not rushing to get a bid in without looking into the sites and then quoting a higher price for the job.
