​Business One Add-On for Technical Consultancy Company

We are an engineering consultancy looking to move to B1. Are there any add-ons for engineering/technical consultancies or professional services companies? I would also be interested in a B1 consulatnt/VAR that specializes in this type of company. I'm appealing to this community because this particular topic is very hard to search for due to the keywords involved.

Thank you for your help!
