Here's my off-the-cuff analysis based on the limited information you've provided: Keep it. The consulting business is worth very little, I think you're right to view it as "selling a job". Take it out of the equation for now. You have $25k - $35k in passive product-based income. That's your sellable asset. So what's it worth? Three years of demonstrated profit would probably be a fair selling price. Based on that you're looking at about $75k pretax. Why do that when you can just sit on it for three years, realize the profit, and still have a business that generates income? If you don't want to do any more consulting work but have recurring business coming in, consider finding a trusted developer who can assume your clients and will pay you a commission on future billings.
