Hi Jo,
High speed Internet is getting more available, currently the ICE has plans for expansion of the service to Quepos in the last half of this year. Look here
Costa Rica Broadband Internet Access for links and info.
Everyone should be aware that there is a new Immigration law coming into effect that makes being a perpetual tourist more difficult, particularly finding work because it carries sanctions for those who house or employ illegal immigrants, which would in theory include people here legally on a tourist visa which does not allow you to work. We don't know how Immigration will enforce the law though.
The good part is that it may be easier to obtain a work permit, and if you have your own Internet based business you won't have to worry about being an employee.
Childcare is relatively inexpensive, you can hire a live-in maid to help you with cleaning, cooking and baby sitting for about $250 per month. It is a great option if you are working at home, since you can monitor your help.
Renting in an area is a good option if you haven't spent much time here. The rental contracts are for a minimum of 3 years, but the renter is able to get out of the contract. If you give 3 months notice, you may terminate the contract and should get your security deposit back. You may also get the owner to put 1 month in the contract or to take a 50% deposit.
