Of course. I don't think self-voting has ever been an issue for me during my time on Steemit. If you're worried, you can keep an eye on the percentage using SteemReports. Yours looks great, of course: http://www.steemreports.com/outgoing-votes-info/?account=calumam&days=31

I think you're doing just fine, so I wouldn't worry too much. If people think your initiative is valuable (it is), you will get delegations. Good luck!
