Anyway - that aside this is an absolutely brilliant idea and fixes a real pain point for me. After spending so long on the app that I've started to hate it, doing all the screenshots, videos, etc. is bad enough - but then you have to do the website as well and it just makes you feel like - "urgh, really? CSS mangling time? Blergh." I would easily pay some of my hard earned indie cash to just have it done for me. Some thoughts:
- I'm going to want to integrate whatever site you create into my own website, so I just want to download whatever you have and throw it into a div container and have it work. Which means there shouldn't be any/many dependencies on CSS frameworks / JavaScript etc. It should be clean.
- If I'm going to give you my cash I'm going to want to be able to choose from a LOT of different themes so that I can differentiate my app from all the others out there. I don't mind doing some of the simple customization myself (colours, text, etc.). I'm not going to want to pay each time if all it comes down to is changing the logo / picture / text when I could easily do that myself.
- I don't know how you plan to monetize, but I wouldn't pay monthly for this. I just don't churn out apps fast enough (other people might want to though, of course). But I would be prepared to pay a fair bit each time if it looks good enough. I'm thinking £5 for the simple demo shown (chow.appsites.com), up to £25 for something like http://staticapp.co/ - with all the fancy animations and the like.
Anyway - hope it works out and you do well.
