There is not enough information in your post to offer any serious suggestions. What is the product you currently have in the market? Did it require special domain expertise? What happens if you decide to close the doors--how would it impact your current customers? Is there any potential for expanding your market? Why would someone want to buy your company? What is the company culture like? Could you could accept outside direction and management? Detailed answers to many of these questions are likely to not be appropriate for a public forum like HN. Your profile has no email address for contact.
