I also did not want to buy from a large commercial hatchery, for several reasons. One is that folks here on BYC seem to feel that the big hatcheries, regardless of whether a breed is labelled "dual purpose", breed them to be better at either producing eggs OR at growing big for meat, but their ability to do both is limited, compared to a breeder or hatchery that is really trying to produce a bird that really does do it all.  The logic makes sense to me, as from what I read here, people tend to get egg breeds and meat breeds separately. As did I. 
The same applies if you want hens that will lay fewer eggs but keep it up for more than two years. Big hatcheries specialize in, well, specialization!
Nw that my hatchery "RIR" hens are two and a half, their egg productivity has fallen off a cliff, and I now will be feeding them for however many years they live, without getting much return in terms of eggs. (YOurs sound about like mine, in terms of color). The girls are too scrawny to eat, anyway - I know this because as they molt, I can see how scrawny they are!
So - I shopped around, posted on BYC, read everything I could find (Feathersite is an excellent resource for learning about different breeds). I eventually found the Sand Hill Preservation Center, which is dedicated to recreating the heritage breeds. They have many breeds available, especially if you're looking now for the spring. I wanted a dual purpose bird that would also raise the next generation for me. So I got a batch of Dorkings from Sand Hill this fall. They're only five weeks old, so I can't speak to the long-term quality of the birds as yet, but they are healthy and active and friendly and so forth. 
Read the signature lines of BYC posters, as they often list the breeds that person has. When you see one that interests you, send a PM. I got lots of good information this way, which helped me narrow down my choices.
Good luck, and use BYC - it's one of the best resources out there!
