Time frame of graft to implant? (Photo)

I have to have tooth 30, and 20 extracted. Can a basic socket graft packed with just Mineralized Cortical bone hold for me to finish the following year(not 6 mths) I do not want to need another graft due to how long I wait. Are another question is can placement be done at the extraction, I would think will save me on cost big time and time? I would still need to wait for the final seat and cost to go to next year. So in order to manage the cost what is the best option Healthy everythin no smoke
