Welcome to DC, Aaron!
Like to help, but need more info:
Where do you live? This, maybe more than anything else, will dictate the going rate for your services.
How much experience do you have? Will you be doing "wash and waxes" by hand; are you proficient at paint correction using rotary and orbital polishers; or something in between?
Mobile or fixed location?
Who is your "bread and butter" client... high end daily driver owner, soccer moms, dealership, show car guys?
Part-time or full-time?
How extensive is your equipment? Buffers? Extractor? Steamer?
Will you be using OTC, mid-grade or boutique products?
Are you licensed, insured?
You can see that this is a rather difficult question to answer without a little info.
Good luck!
