Tomasz,
I understand that you want to come off as a larger company, however, in the situation, YOU are the product! Your customers will benefit from YOUR expertise and YOUR personal service. I think that`s your pitch. It would make me very happy to know that the expert will be personally helping me, instead of someone less capable. Until you have another person working with you, and you post their information/credentials on your site (building your client`s confidence in that person as well) I think you should promote your company as an I; not a WE/US.
My second recommendation was already brought up - refer to the company, not you. Just keep it third person. That`s what I did for my brochures.
