If you are in the market for a commercial photographer, there are a number of elements to consider.

1) Decide what type of commercial photography you will require. Are you looking for architectural photography or trying to illustrate a service? Are you shooting on location or do you need a studio setting? Are you focusing on people or products?

2) Request for proposal. Provide a list that is as specific as possible delineating the photoshoot objectives shot by shot. Will all the shots be in the same building or area? Will some of the shots be off-site? Are there any time constraints that need to be communicated? 

How soon will you need the finished images? Does the vendor have the technical knowledge to shoot to specifications provided by the client's home office? Does the vendor have the bandwidth to take on your project and fulfill it within your expectations?

3) A site visit. If possible, have the photographer do a site visit prior to the shoot. You will gain immensely in the quality of the images, execution, and potentially more setups, by utilizing the walk-through as a dress rehearsal for the real shoot.

4) Usage rights. Check if there are standard criteria here. In general, if no agreement is made prior to the shoot, the photography vendor has a legal claim to the intellectual property value of the photo. This is a critical point that needs to be discussed first. 

Decide in advance what you think your project will need in terms of use and consider asking for a purchase or unlimited use clause in your contract. Expect to pay extra for this privilege.
