I am sorry you are having trouble finding good workshops in your area. Workshops can be very motivating and that is what I sense you want/need.
I use to be an assistant at Friends of Photography workshops in the Carmel/Pebble Beach area...usually one workshop a year (and usually in the Fall). I did not do much photography in the summer as I spent my time packing mules and building trails in a wilderness area all summer. The workshops provided me a huge jump start for photographing/printing through the winter. One learned some technical stuff at the workshops, but what they did for me was get me around other photographers who were producing incredible work. Faculty like Ruth Bernard, Morely Baer, John Sexton, Kate and Geir Jordahl, Linda Conner, et al..and also other assistants like Elaine Ling, Stu Levy, Dan Burkholder, and Christopher Burkett. One could not but be energized from being around such people.
Such quality workshops are hard to find anywhere, let alone in Iowa. My suggestion is to take the initative and create something that will serve the same purpose. Try to connect with other photographers in your general area (also post on
http://www.largeformatphotography.info/forum/ ) and see if you can gather some photographers together to meet and run a mini-workshop. Find and rent a hall, get some lights and backdrops, and have an all-day get-together. Show prints, do some portrait set-ups, etc. Try to find one or two experienced photographers would would be willing to give a short presentation (30 minutes or so) on a particular topic of interest (table top photography, etc).
The Northwest Photo group did just that with an emphsis on alternative photography up in Oregon.
I know how frustrating trying do do one's photography and have a family at the same time. I am a stay-at-home dad to triplets. When the boys were just babes, I took SX-70 images, when they got a little older I used my Rolleiflex, then by the time they could run around in the woods without me keeping an eye on them all the time, I could do my 8x10 work -- with them as my models occasionally. But now we are in another phase -- sports...which eat up a lot of photography time! In another year I will have three teenagers in the house...always more challenges.
I always tried to juggle and never had much luck. Then one day, after changing three sets of diapers, bottle-feeding three babies at one time, and all that other fun baby stuff, I picked up three small balls, tossed them in the air and started juggling...surprised the hell out of me. So now it is just a matter of keeping everything moving...and if a ball, or a chance to photograph, falls...no big deal, I just pick it up and get it up in the air again.
Good luck!
