Angel groups don't necessarily get that involved. You would want to look for angels that have that background and are looking for active engagement with it's clients.

I actually work in this space on behalf of some investors if you would like to talk.

If you're looking for hands-on help with your marketing & sales efforts, I think joining an incubator would be a better fit than looking for angel funds. Angels tend to be less involved in the day-to-day operations of their portfolio companies.

Some incubators have a dedicated team that can help you with sales & marketing initiatives. For instance in Europe you have eFounders that brands itself as a startup studio, providing lots of services. However, this can come with steep ownership expectations (sometimes up to 50%+ of your company).
