if you were up here in dallas i wouldn't mind having an assistant
for your later question, most of my shoots last year were TF* (trade for print/cd/etc). i found all the models on modelmayhem.com. this year (my second year) has been much better for paid gigs for me.
don't worry about it being awkward in the beginning. i was the same way. it was a new thing and i wasn't used to telling people how to pose, or even knowing how i wanted them to pose. so, i used that modelmayhem site and made lists of poses i liked and would refer back to that when i didn't know what i wanted next. the more shoots you do, the easier it gets though.
just remember, -you- are the director (unless you have someone there just to direct

) and the models/subjects (usually) know this. they're expecting to be told what to do, so don't be nervous about ordering them around.
i've also found it helps to do a few test or practice shots with non-professional models first. they might be usable, they might not. the goal of those shots is to see how well the people take direction and to get them a little loosened up before you -really- start shooting.
another thing you can do is attend a workshop. usually the lighting is all setup for you, you'll be able to see how others direct the model, and you'll get to take some shots yourself. i took one that tracy hicks put on up here with greg woodson last year and it was the best $ i ever spent.
