There is a huge difference between people wanting to view free stuff vs those people actually willing to pay for what was previously free. I would suggest googling phrases like "free to paid conversion rates" and reading up on it. Based on most of the research done into this you will be lucky to get 1-2% of your current free viewers to pay. Next is the issue that payment processing fees are quite large, making it unrealistic to charge small amounts like $1. You would look a big chunk of that in fees.
Most of the sports/event shooters who work professionally agree that the only way to get paid (a worthwhile amount) is to be paid by the organisers (who then use the images to promote their events). So get paid to shoot and give the pics away for free.
As for answering your actual question I don't know of any sites/systems that do it but if you google "website pay wall service" or words to that affect you may be able to find someone who can provide what you are looking for.
I agree with you about conversion rates and $1 fee minus per transaction charge & transaction % being taken out. You are looking at around 60 cents on a dollar with just credit card payment fees.
What you want to open up is a membership website (ie. porn site just without porn and wrestling pictures instead). Credit card companies do not trust membership websites as much as other types of businesses and therefore charge higher %. Membership websites also tend to have a higher percentage of chargebacks. There are many options for existing membership website software that can be purchased and installed on your website. You would need to have a merchant account that the software can support to accept payments and within the software you can create membership types and put restrictions on your content.
Membership websites make money on volume and mostly from recurring payments. As Dan mentioned typically they convert at 1-2%. That means for every 1000 visitors you will get 10-20 sales. Lets assume that because of your super content that is highly in demand you will get 10% conversion (100 sales per 1000 visitors). 100 people make a payment on your website and you get $60. There is also additional expenses that you have to pay for in advance and will reduce the $60 of profit even further. There is ongoing cost of web hosting, cost of web design, cost to advertise, cost of membership website software, domain registration, company formation fees, taxes, professional fees, etc. Lets hypothetically say this additional cost over 10 years will be $10,000. If you allocate 10 cents of each transaction to repayment of this amount you would need 100,000 sales over 10 years to be making full 60 cents on the dollar. For first 10 years you would be earning 50 cents on a dollar.
So using my inflated conversion rate of 10% (5-10x normal) and earning 50 cents per transaction and from 1000 visitors you will earn $50. If you have 10,000 visitors you will earn $500. Maybe you take pictures of female mud wrestling and can get 10,000 people but for regular wrestling you will not get that much interest in the day when information can be obtained for free online. You should also ask yourself why would people pay to view pictures of wrestling instead of videos?
