Definitely don't be a jackass like some other commenters have suggested and punt it off on a pre-existing website/business. $2,500 spare is more than enough to launch your own business, and you don't have to worry about dishonest sellers on sites like Flippa inflating analytics/revenue and swindling you out of your hard earned cash (which is a common thing).
Read up on a couple methods; I won't tell you where to look for that, see if any free guides here align with your current skills, and build a brand around that. If you're smart, you can honestly probably get away with doing this for half that and put the rest away for a rainy day.
