Other options to consider are selling your land with owner financing which makes it easier for people to afford. Trying to find cash buyers can be difficult depending on your asking price and banks don't typically want to lend on vacant land. Also, if you have land you want to sell in a hurry and you'd like to get cash for it there are a number of wholesale land buyers that make be interested in making you a cash offer for your land.
Now, far be it from me to discourage using an agent.  This certainly is the easiest way and not necessarily the least profitable or most expensive, especially in a booming market.  In a less-than-booming market however, it’s good to remember that listing your property with an agent will subject it to comparison with dozens, perhaps hundreds of other listings, all competing with yours in features and price. Selling your property then, will probably require that a potential buyer finds it to be either the best he sees… or the cheapest.
Part of the reason for a title company is not only to help facilitate the closing, but also to make sure everything is prepared properly, and (perhaps most importantly) to be a mediator who can handle the documentation and transfer of funds (making sure both parties do everything completely, and that you actually get paid). If there’s no title company involved with this closing, I would be sure your dad and the mortgage company get paid either before or at the same time your dad is signing his documents, to ensure that everything is completed, and you/he actually gets paid.

Nowadays all of my favorite software packages come for the same price: free.  So I’d check out what’s available at tucows.com or software.com.  You can also make a tolerable web page using Microsoft Word (which probably came loaded on your computer) however, if you’ve never made any web pages before, you’ll probably also be needing  web-space to put them on, and you can find both web-authoring software and web-space available cheap or free with a little thoughtful web-searching.
In terms of paying off the mortgage, you’d have to work directly with the lender to make sure they get paid and that they discharge their mortgage. If you’re unsure about how the process works, then honestly – it probably is best to just work with a title company. It may cost a few hundred dollars more – but for a property like what you’re describing, that’s what I would be doing anyway (I use title companies for anything in excess of $10K). They will take all the guesswork out of this process and make it WAY easier to get the job done.
If there’s a lot of money involved in this deal (like, more than a few thousand dollars) and if you’re AT ALL unsure about their level of competence or trustworthiness – then I wouldn’t hesitate to push for a professional title company or closing attorney to get involved. That will resolve pretty much all of the issues that can come up in this kind of scenario. If you don’t know them well, then you have every reason to be skeptical for your own sake.
If Mark has more than one piece of land to sell per week, or if he has exhausted his buyer’s list, he posts raw land investing deals to Craigslist. “Craigslist is the 10th most trafficked website in the US,” he said. “We use a program called Posting Domination. I’m able to automate 124 postings a day, all at the click of a button. It’s unbelievable. So we sell everyday on Craigslist, and we are building our buyer’s list everyday on Craigslist.”
You can also look to certain companies and organizations that have a concentration of people that may fall in the above mentioned roles such as investment companies (i.e. Charles Schwab, Fidelity), financial advising companies (i.e. Morgan Stanley, Merrill Lynch). There may be a higher concentration of people who can both afford and want to build their own custom homes or to build income-producing properties. Try linking yourself to financial advisors who may already know of people who have these types of dreams. This isn't a comprehensive answer of all the possibilities but just some thoughts. Good luck!
