We're really not trying to shoot you out of the water. You need to see the HUGE picture so you CAN succeed.
It's reasonable to expect studio costs in your area to be $3500 (probably more, but...) You will need to make a minimal living so we'll say you have to have $750 AFTER TAXES to survive per week or GROSS $4945 per month. So your overhead is now $8445 per month. And you have 6 months of down time for seniors and weddings...
Your overhead is now $16,890 PER MONTH to cover those off months.
Is that feasable? Maybe. It's going to mean you do a wedding a week AND that you can put that wedding out for proofing in less than a week during those busy months.
One way to get around the time issue with weddings is to produce PROOF quality images in a week, a proof album to share. Then they at least have their images to share with everyone. Include a small sized digi so they can share that and promise their specialty work and albums at 6 months out. That gives you the ability to keep the client happy and then put the heavy duty time consuming work of high end edits and album designs off until your heavy season is gone.
