I don't think that $1000 is to much for a service like this. Having worked with many non technical founders I know about their pain of finding someone who builds a landing page for a reasonable about of money.

I also know quite a few solo founders with a technical background who have pretty shitty landing pages, even though they know (technically) how to build one and/or extended one from themeforest. They just forget about white space, proper padding and stuff, but hesitate to hire a designer for a day.
