Horizon is probably your best choice for that trip.
They have a base in Antigua and St Martin.
We did that trip a few years ago. Just two of us on our Bavaria 50. I think all in all we cleared in and out of 7 countries in a week. Didn't have much time for anything other than clearing in and out, but it was fun.
USA to Antigua to St kits, to Nevis, to St Barts, to St Martin, To Anguilla, back to St Martin and then back To USA.
