Sorry, I can't advise you privately on this. I don't buy/sell websites any more and I don't sell businesses, I'm not a broker.
I provide a niche advisory service for larger businesses (minimum £5m in turnover or £500K in PBT).
But I can advise you here in the thread.
"still healthy" doesn't mean anything. First you need to deduct £30K or £40K for the work you're putting in. The profit is only what's left after paying that salary. And if everything else adds up, and there aren't some horrible hidden risks (99.9999% your "business" has huge hidden risks), you'll probably see offers of 6 months to 18 months worth of earnings when/if you put this up for auction.
If you work alone, you're not really selling a business, you're selling a job. As with selling
anything you need to know who your target customer is. In your case, your target customer is
not people looking to buy a business. It's the average muppet who has a few bucks and who fancies giving up his job and trying his hand at an online business. Or a family with one breadwinner where they are looking for some time-pass activity for the stay at home partner.
I have a website where I posted a lot of information on buying / selling online businesses. I haven't updated it in about 20 years, but you'll still find relevant and useful advice there. The site is
here.
A lot of people use Flippa. I know Flippa far better than most people do. I was trading on Flippa before it was even named Flippa (when it was a Sitepoint marketplace) and I was the biggest operator there at the time. I have a huge amount of data and analysis on what goes on at Flippa (including all the shill bidding). If I tell you here what I think about how dodgy that platform is, if I give you my honest opinion, I'll be inviting a defamation lawsuit. But there are numerous website brokers, there are sites like empire flippers and there are the usual
business selling portals I've listed here.
