I cannot recommend a contractor but I would recommend that any system be designed to NYSERDA standards by a NYSERDA qualified installer. NYSERDA is obviously New York State not CT but NY pays some generous incentives for wood heat and they wanted to make sure that the money was well spent to assure a minimum standard installation to ensure that the money was not wasted. If you have the time it may be good idea to run the this free video course that NYSERDA contractors have to take.

Its free and is given by arguably the most qualified guy to give the course in the US. Yes some of it may go over your head but John S explains things real well.
You did not mention what brand of wood boiler you are considering but many of the distributors require a qualified contractor to install their equipment for the warranty to be valid. If for example you are considering a Froling or an Effecta give Tarm Biomass (the distributor in the US) a call and ask them. They may be able to direct you in the right direction.
An upfront FYI, properly designing a biomass system integrated with an existing heating system is fairly complex and most oil/gas heating companies are clueless. Unless the designer is working for free, the designer has to spend a lot of upfront time on the design. Most of us on this board figured it out ourselves, so its not rocket science and when it screws up we figure out how to fix it since we designed and built it. If you are buying a system from someone else you have not had to understand the design and therefore may be dependent forever on techs to maintain and fix your system, therefore you need to partner with a firm that is going to be around for a long time. They also need to supply you good documentation including a functional description on how everything works so when something stop working a technician unfamiliar with the system can read through it and use it for diagnostics. Most heating techs will generally refuse to work on wood systems.
Inevitably the best person qualified to design and install the system is not the cheapest. Unfortunately someone can not just sell you a design package unless they are a PE licensed in CT and CT is PITA to get a PE for an out of stater. Thus to avoid a PE you end up with a plumbing and heating firm that does the design on their own and install its then ends up with the liability for the whole system. Nothing wrong with that if they know what they are doing but as discussed few do.
The other standard caveat is unless you have a wood supply cut split and properly seasoned its going to be two years before you can run the system to its full potential. Unless you buy wood at a major premium from a wood supplier with a kiln for drying the wood, its highly likely that any wood you buy no matter how dry the firewood seller claims will need a minimum of another year of proper seasoning before its dry enough for the boiler to run as designed. In my area firewood sells for about $225 to 250 a cord while kiln dried is $375.
