Integrate Raiser's Edge with website

Hi, my charity launched a new website 18 months ago and had hoped the agency we used would integrate our RE CRM so that things like online donations and mailing list sign ups etc. could be automated. Sadly, they have been unable to do as they promised and we're now left with some very manual processes, exporting data from our website and slowly and manually importing it into RE. We have used Online Express in the past (on our old website) but found that we didn't have a lot of freedom in making the customer facing form look/perform in the way we wanted it to, so we moved away from that. So, I'd really love to know - how does everyone else automate the process of moving data from your website to your Raiser's Edge CRM? I'd really appreciate any recommendations for developers who can help or a third party software that can solve my problem. Thank you in advance!
