Could you correct it please?

Hi,

It's still for someone who makes an advertisement for an investment company, and I'm not used to some expressions in this area:

"...We work with business companies’ management projects and we are always lined up to our client’s goals through an accounting, juridical and administrative support, creations of projects and marketing strategy...."

Thank you in advance.

Easy,

How about this? I am not exactly sure what you meant by 'line up'.
We work with companies' management projects and help achieve our clients' goals though accounting, legal and administrative sopport, project creation and marketing strategy.
