You need to be very careful not to get in over your head or wallet on this. If your contract allows for all of your expenses [codes,insurance, equipment,x-ray/ut etc services]as well as a reasonable profit for your time go for it.You should be prepared to spend endless hours resaerching particulars because they may be counting on you to "take their word " for things and that is a recipie for disaster[for you anyway] you do not want to become the third party fall guy. If everything checks out and you feel that you can comfortably cover this and your rear end and your expenses and the rest of your life go for it because experience can be the most expensive thing of all. Good Luck John B
