Hi,I'm a uk based lawyer (also doing a start-up - looking for a co-founder), in the UK we have a free council run service for small start up businesses called "Business Link", is there anything similar in the US for you? If not, I think if you pick up the phone and call 3 or 4 law firms, explain that you're a small start up doing whatever and ask if they know anywhere/one that can help you for free at this stage. You should try and avoid paying legal fees just yet. If it were me, I would pick a very large, prestigious law firm, get some email details for attorneys in the corporate/business areas and email them and ask if they can recommend where you can look for some free guidance at this early stage. They are often quite helpful and like to assist if they can. Hope this helps.
