While the web is one way to approach this, and IMO a web site would certainly help for displaying your skills, I was really thinking of people marketing their talents in the communities they live in as their primary source of business. I have been after my son (the human sloth) to do this for a while now.

The plan is fairly simple... Take an old photo and restore it to pristine condition. Now layout a design that shows the before and after along with contact information and anything else you think is important (IE. we also make custom greeting cards, calendars, etc.). Make about 20 prints of this on high quality photo paper, and mount those on some single weight matt board. If you want to get real fancy allow enough space on the board to attach a business card holder, so your cards are easily available to potential clients. Now make a trek around your community to find all the places that allow people to post personal, and/or small business ads on a public bulletin board. Make sure you ask permission and find out any pertinent details. Usually these type of bulletin boards are found in supermarkets, drug stores, libraries, etc... My guess is that a project of this nature would cost about $30.00 to $50.00 in materials plus your time. This is a really low investment for the potential return.

I would also consider advertising in whatever small weekly papers are in your area. Generally the rates in these papers are quite low, and (more importantly) the are well read by older persons (the people most likely to want this type of work done).

Now add a web site into the mix that focuses only on the services you are going to offer, and displays them well. I do not think that I would try to sell this service directly online at first. The site would be more of an online portfolio that emphasizes you talents, and provides contact information for potential clients. Again this is a low investment (except for your time) proposal. Setting up a commerce site is fairly involved and is something I would rather see people grow into as opposed to attempting right off the bat.

The only area left is your pricing structure...

My suggestion here is that you call around to any local businesses that offer this service and get some quotes. The best way to handle this is to go to their establishment with an old photo in hand, and ask for a quote. Armed with this information, you can set your pricing to be competitive without screwing yourself, or your clients. Keep in mind that aside from your time there is also materials involved, and that all businesses have a markup on the materials they sell as part of a project.

Well that's it for now. I think if anyone is interested in this, there is enough here to start the wheels turning.
