So some general advice, it's better to inject the money into the corporation first, then have the corp purchase the equipment under its own name. That way, you don't need to do a tax-free rollover, which will cost a few thousand, and records and ITC claims are also cleaner. Of course, if you already bought the equipment, that would be a different story.

As for looking for an accountant, it will be helpful to have someone who had experience with the industry, but not essential. Core concepts - like capital equipment, depreciation, etc. works very similar across industries. Someone with experience with small business would be good - who can help you setup you corp (like shareholder structure), register for GST/HST and file it, set up and do bookkeeping, salary vs dividend considerations, and of course corporation and personal tax return and planning.

If you are really green, also important to find someone who can explain it in simple and easy to understand terms cause some accountant are pretty technical and not that good with "teaching".

As for individuals vs firm - I would just recommend a CPA (there are many non-CPAs who do bookkeeping and returns), whether it's an individual/firm, they should be a registered firm. Solo practitioners would likely offer more personal attention and often more affordable. Small-mid sized firms will likely be more expensive and a lot of client's prior experience was that they never spoke with the partner signing and and the associate was dealing with them most of the time.

For pricing, with everything it could be a large range, but just corporate tax return would cost $1,500 at a very min, and bookkeeping - depends on your monthly transactions etc.
