I know that this question has been asked more than once and I kind of know the answer at a high level, but I believe that my specific situation is different enough to ask.Background - I am a programmer working for a large financial company. Strengths are vast programming experience (since age 10-11 in the late 80s 
), quick learning,skillset is Java/J2EE/Javascript/SOA and whatnot all that nice corporate stuff, college level C/C++, and some .NET. I have a few ideas for Saas / eCommerce / Social solutions that I want to create and host to see which sticks. My solutions will be computation heavy and will definitely definitely need to expose REST services in addition to the usual data access layer and business logic.I am considering writing these solutions in PHP/JQuery/MySQL for reasons - inexpensive build host and running costs initially (biggest reason) - time to develop (PHP is less verbose) might want to create more than one solution. - supports all the stuff that I think I will need to build the solution.- database/REST/future eCommerce - Makes no difference to end user experience which matters to me. - possibly cheap to hire support in the future.So bottomline, my primary concerns are money , money , time and quality of user experince (all equal).And I am a little worried about - Scalability. - Will I for any reason need to switch to Java in the future. - Being new to PHP although I've read the manual end to end and I'm confident that I will pick it up quickly and be productive fast. I just don't want to spend more than a month or so to get the proof of concept out.Biggest reason I didn't go with Java is the hosting cost, lack of good cheap hosting, and inexpensive J2EE servers, second biggest is time and cost to develop. I would appreciate any and all advice on this. Thanks!
