Someone already mentioned Demand Studios, which is good. They pay weekly and I know several moms who write for them full time. Also look into
Break Studios,
NAA (go through the "support a ticket" link to inquire about freelance writing--they frequently hire, but never advertise) and
QualityGal.
All of the above are content sites, but the following will give you general leads and information on private clients, revenue sites, higher paying gigs, etc:
Freelance Writing Gigs
No Job for Mom
Constant-Content Besides freelance writing, you can also sell some of your photography here.
Inkwell Editorial
For general info on work at home jobs for moms and ways to make money online, these sites may help:
Work at Home Jobs for Moms
My Lil Gold Dress (Be sure to sign up for their free ebook, which is full of useful tips that aren't featured on the main site).
Work at Home Jobs Community (An informative site that also features a forum and blogs that are all devoted to working from home).
WAHM is also a sort of mecca for work at home moms and work at home mom wannabes.
I've heard mixed reviews about Cha-Cha, but it appears to be profitable for some, so it may be worth a try. Also, with regards to the transcription jobs, I understand that regular transcription is a tad bit easier to break into than medical transcription (I'm assuming this is because MTs must also know medical terminology, but I'm not sure). Try
QuickTate and
CallRevu, as well as search for transcription jobs on the sites offered here or through CraigsList. (There are also transcription forums on WAHM.com (above) that may offer you more info.
Since you have to act fast, I'd suggest the writing links first, as some of them aren't too difficult to get hired with and they're almost always looking for new writers. Most pay weekly or every two weeks and you can work around your baby's schedule. This is just to secure something right away while looking for other work at home jobs for moms.
Also, be sure to remind your husband of the expense of working outside of the home. I totally understand where he's coming from (just like I totally empathize with your position), but he may only be calculating the income and not considering the output for gas and transportation, childcare, clothing, lunch, etc. After weighing the financial benefits and losses, he may be inclined to reconsider.
Good luck!
