Filling green card through us citizen spouse

I am planning on filing for Green Card through my US citizen spouse and have some questions, maybe some experienced sajha readers can help me with my decisions: 1. Is it worth getting a lawyer? I contacted few immigration lawyer in the area and they charge anywhere from 1500-3000. Whole process looks pretty straight forward but I can't make up my mind if I should get help from lawyer. 2. My spouse doesn't make enough to sponsor me, anyone have experience of filing joint sponsorship for themselves? How do I provide proof saying that my income/job won't change once my immigration status is changed. 3. Any tips or suggestion from anyone who has gone through this process.
