Ditto on all the replies re demographics. In South Central Texas, $150 is too low. After about 6 years of selling quilts & quilted items at a high end, jurored Christmas event nearby, my daughter and I arrived @$6.75/sq ft. ($163.17) for a 59x59. HOWEVER, we scoured the area for fabric and batting sales, and we stayed with simpler pieced patterns to keep that rate down. A more complicated pattern such as yours made from fabrics purchased at the going rate would have be much more or you would be giving them away! A good way to determine a 'gettable' rate for your area is to visit local quilt shops and check the prices on their displayed quilts. We made notes on sizes and prices and then came home and did the math. Good luck!
